    Abstract:

    We discuss numerical methods for calculating time-correlation functions for quantum systems. We review several methods including analytical continuation methods, stationary phase methods and exact enumeration. We present some results for the relaxation of a quantum spin in a fluctuating medium obtained by exact enumeration.
