DESCRIPTION:Modeling of dynamical phase transitions in electronic systems i
 nduced by ultra-fast optical pumping\nSerguei Brazovskii (LPTMS)\nI shall 
 report the recent studies on phenomenological theory of dynamical phase tr
 ansformations in cooperative electronic systems achieved by means of a fem
 to-second optical pumping.\n1. Experiments on charge density waves recover
 ed coherent unharmonic undulations of the order parameter\, critical slowi
 ng down of the collective mode\, and evolution of the particles spectra. T
 he numerical modeling reproduced the dynamical phase transition\, and the 
 waves emitted by “earthquakes” from in depth annihilation events of do
 main walls.\n2. The special case of resonance optical pumping to excitons 
 is realized in systems with a neutral-ionic ferroelectric transition. The 
 modeling of the quantum-coherent quasi-condensate of excitons interacting 
 with the order parameter recovers the dynamical realization of the “exci
 tonic insulator” state and spacio-temporal patterns with self-focusing\,
  domains segregation\, and local dynamical phase transitions.
