STATIONARY PHASE MONTE-CARLO METHODS - INTERFERENCE EFFECTS IN QUANTUM MONTE-CARLO DYNAMICS

As summarized by Hamming's motto, "the purpose of computing is insight, not numbers." In the spirit of this dictum, we describe here recent algorithmic developments in the theory ot quantum dynamics. Through the use of the somewhat unlikely combination of modern numerical simulations and a visualization device borrowed from 19th century optics, the present efforts suggest the existence of an important, underlying structure in the general problem. This structure, verified for a relatively simple class of model problems, provides broad guidelines for the formulation and treatment of the general quantum dynamical problem.
