Stochastic Cluster Series expansion for quantum spin systems

arXiv:cond-mat/0310465 · doi:10.1103/PhysRevB.70.100410

Abstract

In this paper we develop a cluster-variant of the Stochastic Series expansion method (SCSE). For certain systems with longer-range interactions the SCSE is considerably more efficient than the standard implementation of the Stochastic Series Expansion (SSE), at low temperatures. As an application of this method we calculated the T=0-conductance for a linear chain with a (diagonal) next nearest neighbor interaction.
