Monte-Carlo simulations of Ising-like materials: Multipath Metropolis vs cluster update approach

摘要

Multipath Metropolis simulation of classical Heisenberg model has been proposed in Physica A 441, 69 (2016). In contrast to the original single-path algorithm, multipath simulation approach is inherently parallel because it uses different random-walk paths that are mutually independent. To further test the reliability of multipath approach, single flip multipath simulation is tested against standard cluster update algorithm implemented with ALPS libraries in case of exactly solvable 2D Ising model.
