Nonlinear Dynamics and Theoretical Biophysics Lab
[ research ]
 
In 1972, in the Department of Theoretical Physics of the Lebedev Physical Institute, the Sector for Theoretical Biophysics Problems was formed on the initiative of D.S.Chernavsky and with the support of the head of the OTF Academician V.L. Ginzburg. Initially, the Sector was engaged in the research of biological systems, in particular, the problem of the appearance of biological rhythms, the study of possible mechanisms of biological self-organization, the mechanism of charge transfer in biological macromolecules, and the mechanism of the functioning of enzymes. In the future, the range of tasks to be solved has expanded considerably and has gone beyond purely biological ones. A number of important results have been obtained, both of a general nature, concerning the fundamental mechanisms of spatio-temporal self-organization in open nonequilibrium systems and relating to specific systems of a different nature: physical, chemical, biological.

In 2015, the Sector was transformed into a Laboratory nonlinear dynamics and theoretical biophysics. The main area of ​​work is the study of the mechanisms of formation of space-time structures in nonlinear dissipative dynamical systems. Within the framework of this direction, fundamental problems of self-organization are being solved, and mathematical models that describe specific systems are being developed. In particular, recently, the objects of the theoretical study of the Laboratory were complex spatio-temporal regimes experimentally observed in chemical reactions, such as the Belousov-Zhabotinsky reaction, as well as on the propagating combustion front, the growth and progression of the malignant tumor, taking into account its interaction with surrounding tissues and with blood vessels, complex autooscillatory regimes, including dynamic chaos, in ensembles of coupled oscillators

Research interests:

  • waves in chemical reactions,
  • dynamics of ensembles of coupled oscillators ,
  • modeling tumor growth,
  • dynamics and structure of combustion waves ,
  • partial synchronization in neural networks
  •
