CENS KEYWORDS

Nonlinear dynamics

Soft matter physics

Microstructured solids

Solitons

Acoustodiagnostics

Photoelasticity

Biophysics and cell energetics

Surface and extreme waves in sea

Signal processing

Nonlinear differential equations

MAIN RESULTS

Interaction solitons, shallow water

Surface elevation in the vicinity of the interaction area, corresponding to incoming solitons with equal amplitudes but different angles between their crests.

MAIN RESULTS

Interaction of solitons in nature

MAIN RESULTS

Emergence of solitons

Emergence of solitons from an harmonic excitation in force field. After a certain transfer period the emerging coherent pattern is seen with amplified solitons.

MAIN RESULTS

Wave motion and dynamics

Mindlin model for microstructured solids, 1D. Two trains of solitons emerging from a single input.

MAIN RESULTS

Phase transition

Stress wave changes the shape of a martensitic inclusion in an austenitic solid.

Martensite

Austenite

Shift of a phase boundary (green line) between martensite and austenite under localized pulse-type stress load at the left boundary. The influence of shear causes a rugged interface.

MAIN RESULTS

Biophysics

Schematic representation of the biochemical processes in the reaction-diffusion model of the heart cell.

MAIN RESULTS

MAIN RESULTS

Biophysics

Lyapunov exponent map on the para-meter plane for the periodical driven nerve pulse equation modelling cardiac conduction.

MAIN RESULTS

Soft matter physics

A chaotic mixing of an initially smooth field of dye by a smooth chaotic velocity field leads to complex multifractal patterns.

MAIN RESULTS

Soft matter physics
