Open DayThis image shows the plate-shaped hydroxyapatite produced by bacteria. Hydroxyapatite is naturally found in bones. Thus, it is very biocompatible. Hydroxyapatite coated titanium is widely used as implants, such as the hip replacement and some dental root implants. The project we are working on is to use bacteria to produce hydroxyapatite, the main components of bones, on titanium.

Climate sensitivity usually refers to the equilibrium change in the annual mean global surface temperature following a doubling of the atmospheric carbon dioxide concentration. The observed change in global mean temperature is used as one benchmark for climate change and is central to the reporting of the IPCC. However, our perception of climate change and its impacts are local, both geographically, and in terms of which part of the distribution of temperatures (which quantile) is changing fastest.This colloquium will focus on how observational data can be analysed to inform us about how climate has changed locally since the middle of the last century, and what the uncertainties are. One can find a clear signal of large change, a clear signal of little change, or no clear signal at all, depending upon geographical location and quantile. Analysis of the E-OBS gridded dataset across Europe suggests that in those locations where the response is greatest, the hottest summer days in the temperature distribution have seen changes of at least 2 °C, over four times the global mean change over the same period. In winter the coldest nights are warming fastest.

Medical imaging in the form of positron emission tomography (PET) has been available for more than forty years but only in the last decade has it become a widely available diagnostic technique within the UK. Currently all PET imaging in the UK is carried out on PET/CT devices, PET detectors with combined x-ray computerised tomography (CT) imaging capabilities; the exception is the recently introduced PET/MR (Magnetic Resonance) device installed in a London hospital.The radionuclide and equipment development underpinning PET imaging, the imaging environment and techniques, diagnostic strengths and weaknesses and future developments will be discussed. Some example images will be shown.

It is just over 100 years ago since William Henry Bragg and his son William Lawrence Bragg discovered how to use the diffraction of X-rays by crystals to determine their structures, thus founding a completely new scientific discipline, X-ray Crystallography. They both shared the Nobel Prize in Physics in 1915, with the young Lawrence at the age of 25 still remaining the youngest Nobel Prize winner ever. Approximately 24 or so Nobel Prizes awarded since have depended on their seminal contributions to solid state science. In this talk, I shall explain who these important British scientists were and how they arrived at their momentous discoveries that have truly transformed our understanding of the material world.

Experimental cosmology has recently become a precision tool to measure the Universe. The Cosmic Background Radiation (CMB), emitted 380,000 years after the big bang is one of the best tools available today to try to understand the origin of our Universe, where does the matter and energy come from. In addition, the closer we study the Universe to the big bang, the higher the energy involved and so we have the perfect "particle accelerator", at least theoretically. In this talk I will review briefly the history of the CMB, from the discovery by Penzias and Wilson to the recent Planck results. I will then show where is the next frontier - the study of the polarisation of the CMB - and how to use the entire Universe as a Gravitational Wave detector.

The detection and characterisation of exoplanets relies on the identification of incredibly small signals set against noise emanating from our atmosphere and that of the host stars. Observations from space can allow continuous observations over an extended period and allow the detection of earth sized planets. In this talk I will discuss the present and future of exoplanet research primarily from a European (and Warwick!) prospective showing that we are on a path to be able to characterise atmospheres for biomarkers by the end of the next decade.

When the attractive forces induced by the presence of a high molecular weight additive acting as depletant become strong enough, a colloidal suspension undergoes a liquid–liquid (L-L) phase separation that, if the depletion forces are sufficiently short-ranged compared to the size of the colloidal usually gets arrested by the formation of a disordered colloidal solid with a gel-like structure. I shall present a survey of the experimental results on the settling and restructuring dynamics of colloidal gels obtained by Photon Correlation Imaging and Ghost Particle Velocimetry, two novel optical correlation techniques particularly suited to the investigation of the microscopic dynamics of spatially heterogeneous samples. Three distinct regions can be set apart within the L-L coexistence region of the phase diagram. When depletion forces are barely sufficient to drive the system within the metastable region, an initial disordered gel hosts the rapid nucleation of crystallites, which stress the gel structure until it fully collapses, leading to the formation of a macroscopic colloidal crystal. For stronger attractive forces, two distinct scenarios are observed, depending on the particle volume fraction ϕ0 of the original suspension. At low ϕ0, the gel breaks after a short delay time into separate clusters, which rapidly settle until they compact in a denser disordered phase. The latter eventually undergoes a slow compression, which is accounted for by a “poroelastic” model where the microscopic gel dynamics is fully ruled by its macroscopic deformation. Yet, it is the intermediate stage between cluster settling and final compaction which displays very peculiar features, evidenced by anomalous settling profiles which are totally unusual in standard colloidal sedimentation processes. For larger values of ϕ0, gel breaking is conversely suppressed, the structure undergoes a continuous compression, and the microscopic dynamics is characterized by logarithmic time-correlation functions resembling those found for attractive glasses.

Interactions between swimming cells and surfaces are essential to many microbiological processes, from bacterial biofilm formation to human fertilization. However, despite their fundamental importance, relatively little is known about the physical mechanisms that govern the scattering of flagellated or ciliated cells from solid surfaces. In the talk I will reveal recent advances in understanding of flagella interaction with surfaces, provide mechanisms for utilizing our knowledge about these interactions to control swimming of flagellated cells. In addition, I will describe our very recent results on sperm rheotaxis near surfaces. The key focus will be on the experimental results, supported by numerical simulation using minimal models.

The optical and excitation transport properties of a wide variety of systems, such as molecular aggregates, photosynthetic complexes and organic photovoltaics, are determined by the collective properties of the relevant excitations, which are strongly influenced by interactions with their environment. In modeling the behavior of these collective excitations (excitons) in a disordered environment, one conventionally often considers model parameters as stochastic quantities with Gaussian distributions. However, we have shown that the limitation to Gaussian distributions is not necessarily the best choice, and that a generalization to the wider class of Lévy distributions leads to qualitatively different collective optical properties.In this talk, I will discuss how the details of the considered disorder distributions influence the localization properties of excitons in supramolecular systems, and in turn their optical and energy transport properties. First, I will discuss how a generalization to Lévy disorder distributions affects the localization behavior and the absorption properties of the optically relevant exciton states. It will be shown that such a generalization leads to novel effects such as exchange broadening and an anomalous exciton localization. Moreover, I will show that Lévy distributions follow quite naturally from a simple microscopic model. In addition, the modified localization properties are shown to cause a qualitative change in exciton dynamics, leading to subdiffusive (i.e. less mobile than diffusive) behavior of the exciton transport.

Quantum correlated probes have the potential of delivering enhanced precision in estimating individual parameters. Obtaining quantum enhancements in scenarios of wider appeal such as imaging require an understanding of the quantum limits of estimating several parameters across multiple modes simultaneously. The problem is made theoretically and well as practically interesting and non-trivial by the possible non-commutativity of the optimal measurements needed to attain the quantum limits for estimating individual parameters. We present developments on the quantum theory of estimating multiple parameters -- arising from both unitary dynamics as well as decoherence -- simultaneously in a few scenarios, and its ramifications in the imaging of real-world samples.

In the first half of this week's seminar, I will describe my current research before outlining a research project for which I am looking to obtain funding. For many applications it is essential to modify the electronic properties of graphene in a controlled fashion. This can be achieved via oxygen and nitrogen functionalization in ultra-high vacuum, leading to a system in which electronic and structural properties can be systematically studied. We directly compare insights from DFT calculations on functionalized graphene systems (e.g. low-energy configurations, binding energies and effective band structures) to results from angle-resolved photoemission spectroscopy (ARPES) and low-voltage aberration-corrected transmission electron microscopy experiments. Phase-change materials (PCMs) are promising candidates for widely used non-volatile RAM modules. I propose to create an atomistic model of a PCM to illuminate the largely unknown processes involved in fast recrystallisation. These results could then be employed to design a sustainable alternative to the currently used Ge-Se-Te compounds.

In this talk I will discuss two remarkable effects of spin-triplet superconductors (TSC): i) the spin-orbital coupling emerging at the interface with an itinerant ferromagnet (FM) [2], ii) the occurrence of magnetic Andreev states at their edge if the system allows for singlet pairing in a subdominant channel [3].In a TSC-FM heterostructure, the orientation of the FM moment relative to the TSC vector order parameter is a crucial variable that controls the physical behavior. For a single-component p-wave TSC, we find that the variation of the gap controls the orientation of the FM's moment mainly via the change in condensation energy. When the interface is imperfect or spin active the scenario is different and other processes can play the decisive role in setting the magnetic profile [5].Concerning the surface states, novel magnetic effects can occur if triplet and singlet pairing get mixed and have a non-uniform spatial profile. As a result, the Andreev bound states are spin-polarized, leading to a finite surface magnetization, spin current and surface charge currents that exhibit anomalous dependence on the magnetization [3].

In Lanthanide based metals new electronic quasiparticles emerge from the interaction of f electrons with conduction electrons. They are called heavy fermion materials because of the highly enhanced effective mass of these quasiparticles. Great opportunities arise from the good control and tunability of these materials. As such heavy fermion materials provide outstanding access to study competing ground states and the quantum criticality associated with the zero temperature phase transition. Quantum criticality leads to novel states of matter and is discussed to underlie high temperature superconductivity.The prototypical materials YbRh2Si2 features a quantum critical points which requires descriptions that go beyond the conventional order-parameter notion. Here, electronic structure studies played a key role to identify the intriguing physics of YbRh2Si2. I will discuss Hall effect measurements which find a reconstruction of the Fermi surface in the zero temperature limit. Furthermore, energy-over-temperature scaling deduced from the Hall effect measurements indicate that the fluctuations between the two different Fermi surface configurations is underlying the finite temperature quantum critical behavior.The newly discovered heavy-fermion material YbNi4P2 appears to be one of the first examples of a truly continuous quantum phase transition from a ferromagnetic state to a paramagnetic state. Remarkably, this is in contrast to theoretical predictions which exclude ferromagnetic quantum critical points in metallic systems. However, these theoretical considerations are valid for two and three dimensional materials only. I will present electronic structure calculations in conjunction with quantum oscillation measurements. These comprehensive electronic structure studies reveal a quasi-one-dimensional electronic structure which might be the key to understand the presence of a ferromagnetic quantum critical point.

Red giant stars can be stripped of their outer layers by stellar collisions or mass transfer in binary star systems such as low mass X-ray binaries. If the red giant is stripped on its first ascent of the RGB it will eventually become a very low mass white dwarf composed almost entirely of helium. Very low mass white dwarfs are well known in binary milli-second pulsars and many have recently been found in surveys such as the SDSS, but the precursor phase during which the remnant evolves to higher effective temperature at nearly constantluminosity has been rarely observed. In this talk I will present new observations of 18 bright eclipsing binary stars discovered in WASP archive that contain stripped red giant stars. The first such binary we identified was also found to be a new type of pulsating star. This opens up the possibility of studying the interior strucuture of these helium white dwarf precursors in unprecendented detail.

Just two decades after the first discoveries of planets outside our Solar System, we now count over 1000 exoplanets and have been able to investigate some of their atmospheric properties. With the ever-improving technical capabilities, the possibility of finding hot and massive planets has extended to smaller planets (terrestrial) with mild surface temperatures (habitable). The observation of M-type stars is a “fast track” method to discover, and possibly characterise, hot and temperate rocky exoplanets. The CARMENES spectrograph, with its two channels covering from the visibe to the near-IR, is ideally suited for the job. CARMENES will survey a sample of 300 M dwarfs (with special emphasis on mid- and late-Ms) in search for planets as small as a fewEarth masses within the habitable zone of their stars. Besides the technological challenge of obtaining m/s precision in the NIR, the project faces also the problem of having to deal with stars that can be intrinsically active. In this talk I will present the CARMENES instrument, including both the science case and the current development status. In addition, I will discuss our efforts in trying to understand the impact of stellar magnetic activity on radial velocities and possible ways to mitigate its effects.

Despite our understanding of how galaxy form witnessed significant progress in the past years, whether galaxy formation follows different paths in dense regions compared to the global field and whether more massive

galaxies were the first ones to form or vice versa, remain unsolved questions. In fact, while the hierarchical galaxy formation scenario (assumed as the premise of the majority of simulation-based studies) points at more

massive galaxies forming later then less massive ones and at a strong environmental role, the more observationally-supported downsizing galaxy-formation scenario sees more massive galaxies forming earlier

than less massive ones and gives relative importance to environment. The possible distinction between galaxy mass assembly and star formation epochs, the mutual roles of mass (AGN) and environment driven star-formation quenching and the complicated interplay between dark and baryonic matter over cosmic time,

render our understanding of galaxy formation even more difficult. As a result, the way galaxies (i.e., galaxy formation and evolution) influence the structures they dwell in and how structures (i.e., gravity) affect the

galaxies they host, have yet to be disentangled and fully understood. I will explore these topics by presenting studies on the global galaxy luminosity and mass functions (including very preliminary results from the Dark Energy Survey and the Canada-France-Hawaii Telescope Legacy Survey), the Halo occupation Distribution in

clusters and the detection of extremely red z>3 galaxies from the SERVS survey. Diego Capozzi

X-ray spectroscopy provides a unique view of the innermost workings of accretion flows onto black holes. When coupled with variability studies one can, in principle, determine the

geometry of the inner accretion flow, corona and even test general relativity in the strong field regime close to a black hole. I will introduce the use X-ray spectroscopy, and "broad iron lines"

in particular, to study accretion discs around black holes. I will then explain why X-ray echo (reverberation) mapping is in principle such a powerful technique for studying the innermost

regions of the accretion flow, and how in practice it is possible. Throughout the talk I will present some recent (and not so recent) results, and end by discussing the future direction of

my work in this area.Andy Young

Low mass planets orbiting the lowest mass stars are expected in significant numbers in close orbits of a few days to a few tens of days. To date, however, the nearby population of late M stars has not been targeted by precision radial velocity surveys. I will present radial velocity measurements for a sample of M5V - M9V from the Red-Optical Planet Survey, ROPS, that operates in the 0.65 - 1 micron regime.

Radial velocities with r.m.s. precision down to 2.5 m/s over a week long time scale indicate sensitivities to planets with masses >= 1.5 M_Earth in the classical habitable zone can be achieved. In

9/15 of our targets, observations currently rule out the presence of planets with masses >= 10 M_Earth in close orbits.

Late M stars on average show significant rotation, and chromospheric activity is in fact found in a number of the ROPS targets. The implication that most M dwarfs are significantly spotted, and hence

exhibit time varying line distortions, indicates that observations to detect orbiting planets need strategies to reliably mitigate against the effects of activity induced radial velocity variations. I will

also present estimates of detection thresholds for spotted M stars and a new procedure for removing starspot noise.John Barnes

Stellar birth environments are dangerous environments for planetary systems. I will describe how planetary systems are vulnerable to perturbations from passing stars and stellar companions within stellar clusters. These perturbations may lead to a chain of events that result in the ejection of some planets, leaving those remaining on tighter, and eccentric, orbits. Planetary systems may exchange into binary systems and then the stellar companion may perturb planetary orbits via the Kozai mechanism. I will show how this can lead to strong dynamical interactions between planets in a planetary system, with some planets being ejected. In some cases, planets placed on extremely eccentric orbits may form hot jupiters via tidal interactions.By using full N-body calculations of young stellar clusters, I quantify the frequency of both fly-by encounters and binary-exchange encounters,and also the frequency of close encounters involving protoplanetary discs.I compute the fraction of planetary systems likely to emerge unscathed from a stellar cluster.

The bulk composition of Earth is commonly assumed to be chondritic but evidence from measurements of isotopic ratios in rocks on Earth suggests that it differs significantly from that of chondritic meteorites.

The history of the Galaxy is imprinted in the kinematics and chemical properties of the stars in the stellar halo. Their study allows us partially to reconstruct the Galactic past because the time required for stars in the halo to exchange their energies and momenta is very long compared with the age of the Galaxy. This field has been revolutionised in recent years by data from the Sloan Digital Sky Survey Data, which has revealed a super-abundance of substructure. There are ghostly streams from disrupting dwarf galaxies and globular clusters, analogues of meteor streams along old cometary paths in the Solar. There are ultrafaint phantom galaxies composed of old and faint stars, so puny that the entire galaxy is outshone by a single red giant star. There are smooth, flattened, halo populations, such as the blue horizontal branch stars. Dominating the Galactic halo, there is the magnificent double arch of the Sagittarius stream criss-crossing the whole sky. These tracers enable the study of the assembly of the Galaxy, as well as its present-day mass and gravitational field. The quality of the data permit confrontation -- and conflict – with modern-day cosmological simulations of galaxy formation.

Do stars form in basically the same way everywhere? If they do, then we can learn about star formation everywhere and everywhen from studying present-day local star formation. If they don't, then local star formation could be just fluff that might not tell us much about anything. I discuss what we mean by 'the same', and examine what observations tell us that star formation must be like if it is 'universal'.

Core-collapse supernovae are the spectacular finale to the life of a massive star. In recent years, considerable progress has been made in directly identifying the stellar progenitors of core-collapse supernovae, most notably in images from the Hubble Space Telescope. From this work, it appears that there is a puzzling absence of hydrogen-rich supernovae from the most massive red supergiants, while binary interaction seems to be crucial for many (or even most) hydrogen-poor supernovae. I will present the most recent results from the ongoing search for core-collapse progenitors, and compare these to both theoretical expectations and the resulting supernova characteristics.

Eminent physicist Sir Michael Berry will give a lecture entitled ‘Optica Fantastica: images to illuminate the physics of light’ and the Coull Quartet will give the premiere of Cowie’s Quintet for 21st Century Oboe and Quartet ‘The Colours of Dark Light’, a work directly inspired by Sir Michael’s discoveries in the field of wave physics.

Between the lecture at 5.15pm and the concert at 7.15pm, both of which are taking place in the Helen Martin Studio, our audience will be invited to join the Quartet, Edward Cowie, Sir Michael Berry and oboist Christopher Redgate in the Butterworth Hall for drinks, an exhibition of the composer’s drawings, demonstrations of experiments by the physics department and a short introduction to the music. The concert itself, in addition to Ravel’s beautiful and evocative Quartet and Britten’s brilliant, youthful Oboe Quartet, will feature no fewer than four different oboes, including the brand new Howarth/Redgate 21st Century Oboe and the spectacular ‘Lupophon’, skilfully used by Edward Cowie in his music to produce the widest range of colour and sonority.
