Traveling solitons in modulated elastic media

A diatomic elastic chain with nonlinear interparticle interaction placed in a nonlinear external potential is considered. A detailed classification of possible two-parametric traveling gap-and near-gap-soliton solutions for this system is given for different relative strengths of the nonlinearities. Analytical expressions are derived for traveling near-gap solitons in the absence of an external field.

Kinetic theory of bridge processes

The detailed consideration of the kinetic aspect of the bridge process has allowed us to correctly write a kinetic equation beginning with knowledge of system microparameters. The solution of the equations makes it possible to elucidate the character of the relaxation process and to determine its typical constants as functions of those microparameters. Particular attention was given to kinetics in the presence of polaron effects. In this case the standard perturbation theory applied to derive the kinetic equations is not valid. The solutions obtained for this case are different both in the form of correlation functions and in the character of the interaction taken into account.
