Abstract
We calculate in this article the transport coefficients which characte rize the dynamics of solitons in quantum field theory using the method s of dissipative quantum systems. We show how the damping and diffusio n 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 dissipatio n in quantum mechanics.
