Laboratory for Statistical Physics of Complex Systems


Laboratory for Statistical Physics of Complex Systems

The Laboratory was created in 2010.

 

2015: we are 5 years old!

 

Our objective is to study complex systems, i.e. systems composed of many interacting parts, often called agents, which display collective behavior that does not follow trivially from the behaviors of the individual parts. Inherent features of complex systems incorporate self-organization, emergence of new functionalities, extreme sensitiveness to small variations in the initial conditions, governing power laws (fat-tail behaviour).

 

Head of the laboratory – Yurij Holovatch

 

Research

Our research is focused on studies in statistical physics of complex systems. The subjects covered include:

  • static and dynamic critical behavior of disordered magnets;
  • conformational properties of polymer macromolecules;
  • quantitative social science;
  • complex network science;
  • scientometrics.

Methods of studies include analytical approaches (field-theoretical renormalization group, functional integration, resummation of divergent series, phenomenological thermodynamic approach), computer simulations, empirical data analysis.
