Abstract

Abstract Numerical evaluations of path integrals are done for a stochastic model of spin relaxation based on a previous formulation. Explicitly, with the use of stochastic differential equations, the path integrals with respect to the stochastic fluctuating field are performed by a generalized version of the Runge-Kutta method. The computational results are compared with the known exact analytic solutions and fully numerical calculations. The path integral solution is shown to be satisfactory.
