摘要：

We calculate in this article the transport coefficients which characterize the dynamics of solitons in quantum field theory using the methods of dissipative quantum systems. We show how the damping and diffusion coefficients of solitonlike excitations can be calculated using the integral functional formalism. The model obtained in this article has features which cannot be obtained in the standard models of dissipation in quantum mechanics.
