摘要：
An iterative path integral procedure is developed for calculating equilibrium two-time correlation functions of quantum dissipative systems. Its numerical feasibility is demonstrated by studying the position-position correlation function of two-level systems at various temperatures. It is also shown that canonical partition functions are also amenable to an iterative treatment. (C) 2001 Elsevier Science B.V. All rights reserved.
