Path-integral Monte Carlo Simulations without the Sign Problem: Multilevel Blocking Approach for Effective Actions

Chemical Physics 2009-11-06 v1 Statistical Mechanics Computational Physics

Abstract

The multilevel blocking algorithm recently proposed as a possible solution to the sign problem in path-integral Monte Carlo simulations has been extended to systems with long-ranged interactions along the Trotter direction. As an application, new results for the real-time quantum dynamics of the spin-boson model are presented.
