A continuous-time solver for quantum impurity models
Philipp Werner, Armin Comanac, Luca De Medici +2
We present a new continuous time solver for quantum impurity models such as those relevant to dynamical mean field theory. It is based on a stochastic sampling of a perturbation ex…
Cluster Monte Carlo Algorithms for Dissipative Quantum Systems
Philipp Werner, Matthias Troyer
We review efficient Monte Carlo methods for simulating quantum systems which couple to a dissipative environment. A brief introduction of the Caldeira-Leggett model and the Monte C…
Simulation results for an interacting pair of resistively shunted Josephson junctions
Philipp Werner, Gil Refael, Matthias Troyer
Using a new cluster Monte Carlo algorithm, we study the phase diagram and critical properties of an interacting pair of resistively shunted Josephson junctions. This system models…
