Complex Systems and Chemical Processing of Information

Group leader

prof. dr hab. Jerzy Górecki

Research topics

The research of the Group #24 is concerned with systems showing complex spatio-temporal evolution. In particular, we work on identification of stationary structures, phase transitions and characterization of a complex time evolution for spatially confined systems with specific interactions (SALR - Short range Attraction and  Long range  Repulsion type, interactions mediated by concentrations of surface active molecules). We also interested in  far-from-equilibrium phenomena and in applications of chemical reactions for information processing. Our research combines theoretical methods of statistical physics, microscopic computer simulations using  molecular dynamics and advanced optimization methods based on genetic algorithms. We perform experiments  on non-linear chemical reactions (Belousov-Żabotyński reaction) and on the complex behaviuor of objects that exhibit self-propelled motion on the water surface.
