PHYSICS AND MATH BUILDING MASONRY REPAIR STATUS:

Masonry probes were performed in 2003 to determine the condition of the masonry facade, corner soldier brick courses, masonry column enclosures,

The building

y yand relieving angle structures by all the windows.

Scope of Work for the masonry repairs are defined. Budgetary Cost estimates for masonry repair and new roof were completed: $1.86M

We are at the top of the list -- Hoping for the NY State budget to pass!

Over the past year, many repairs made to the AC systems on the roof – new catchment trays for condensate water, redo plumbing. So far, leaks seem to be gone!

17

This year I asked for one slide that represents the work of each of the research groupings. Thus this summary is NOT complete, but I hope that it gives the students a flavor for the research opportunities that the Department offers.

Research highlights of the past year

Organizing principle for areas is from smallest to largest.

Phys/Astro merger

The physics mistakes in presenting these are mine!!

Physical Sciences and Math research expenditures ~ $13.3M in AY’03 (14th in the nation); highest in the university

Old idea (1988), recently revived and extended (December, 2003)New string theories, for just 4 dimensionsActually describe particles, not strings

Twistor superstrings(Nair; Witten; Roiban, Spradlin, & Volovich; Berkovits; Vafa; ...)

Tailored to describe Quantum Chromodynamics (as part of maximally supersymmetric Yang-Mills)

Directly give known simple results for tree graphs (Born approximation scattering)Much simpler than Feynman diagrams; possible replacementUse topology, twistors, superspace, worldsheet instantonsMay generalize to new kinds of QCD stringsWork by Stony Brook people: Roiban (former student); Berkovits (former postdoc);

Siegel (faculty); Giombi, Ricci, Robles-Llana, Trancanelli (students)One of the topics at the Simons Workshop here, “Superstrings & Topological

Strings”, July 26 - August 27, 2004

Stringy ideas are now influencing understanding of phenomena observed in the lab; may lead to ability to calculate complex higher order supersymmetry processes at LHC.

1st DØ publication from upgraded detector

In central collisions the particle production associated with both mesons and baryons in Au Au is similar and significantly higher than observed in pp and dAu collisions. This suggests that baryons are produced in jets, rather than by recombination of thermal quarks.

COLLIMATING ATOMS WITH COLLIMATING ATOMS WITH THE BICHROMATIC FORCETHE BICHROMATIC FORCE

Why the bichromatic force ???

It’s HUGE, and it spans a HUGE velocity range!!!

FOCUSING ATOMS WITH FOCUSING ATOMS WITH A DC ELECTRIC FIELDA DC ELECTRIC FIELD

Why electrostatic forces ???

This is a new domain for atom optics and control.y g p

The bichromatic force offers a new domain ofoptical forces to exploit for control of atomicmotion. Here it collimates a metastable Hebeam to high intensity and brightness for use inatomic lithography. (Thesis of Matt Partlow).

Electrostatic forces act on neutral atomsONLY through an induced dipole moment, aprocess efficient ONLY in Rydberg atoms.Here the Rydberg states (high n) have beenproduced by a novel process and focused toa small spot. (Thesis of Oleg Kritsun).

Note – even though these look similar, they are indeed very different images.

A wealth of exciting physics and astronomy has emerged your work over the past year. I have only scratched the surface (more reports to come in colloquia seminars surface (more reports to come in colloquia, seminars, Friday presentations)

The students, research associates and faculty at Stony Brook are recognized as being at the leading edge in many of the most important areas of science.
