Solitons in stochastic molecular chains


The dynamics of solitary collective excitations in one-dimensional molecular crystals under the action of stochastic perturbations is studied. An equation is derived for the mean field of nonlinear collective excitations a(x, t) and deformation of the lattice ρ(x, t). The law describing the decay of collective excitations is obtained.
