Abstract

The computation of multitime correlation functions of a quantum system coupled to a dissipative bath of harmonic oscillators was done by an iterative path integral algorithms. Reordering the propagators and splitting the Boltzmann operator into two in the expression for canonical correlation functions, led to transformation of the evolution time contour into a symmetric one so as to specify forward propagation and a backward one. The results showed that the correlation function could be obtained by using iterative procedure.
