Stochastic Cluster Series expansion for quantum spin systems
Kim Louis, C. Gros
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 effici…

Quantum Monte Carlo simulation for the conductance of one-dimensional quantum spin systems
Kim Louis, Claudius Gros
Recently, the stochastic series expansion (SSE) has been proposed as a powerful MC-method, which allows simulations at low for quantum-spin systems. We show that the SSE allows…
