Title: Continuous-time hybridization expansion quantum impurity solver for multi-orbital systems with complex hybridizations.
Authors: Shinaoka, Hiroshi1,2 shinaoka@mail.saitama-u.ac.jp, Gull, Emanuel3, Werner, Philipp4
Source: Computer Physics Communications. Jun2017, Vol. 215, p128-136. 9p.
Subjects: Impurity-dislocation interactions, Impurity distribution in semiconductors, Monte Carlo method, Programming languages, Simulation methods & models
Abstract: We describe an open-source implementation of the continuous-time hybridization-expansion quantum Monte Carlo method for impurity models with general instantaneous two-body interactions and complex hybridization functions. The code is built on an updated version of the core libraries of ALPS (Applications and Libraries for Physics Simulations) [ALPSCore libraries]. Program summary Program title: ALPSCore CT-HYB Program Files doi: “ http://dx.doi.org/10.17632/dyhhx6g4md.1 ” Licensing provisions: GPLv3 Programming language: C++ , MPI for parallelization. Nature of problem: Quantum impurity problem Solution method: Continuous-time hybridization-expansion quantum Monte Carlo External routines/libraries: ALPSCore libraries, Eigen3, Boost.
