We present a method for the computation of time-dependent quantum correlation functions. We calculate the temperature dependence ofthe correlation function at zero time and analytically continue to obtain the time dependence at finite temperature.
A review of the basic strategies that we have developed for the simulation of dynamic correlation functions in quantum systems is provided. Three methods are considered: (a) the analytic continuation of imaginary (thermal) time correlation functions to real times; (b) direct evaluation of thermally
