A Multigrid Algorithm for Sampling Imaginary-Time Paths in Quantum Monte Carlo Simulations
C. H. Mak, Sergei Zakharov
We describe a novel simulation method that eliminates the slowing-down problem in the Monte Carlo simulations of imaginary-time path integrals near the continuum limit. This method…

Relieving the fermionic and the dynamical sign problem: Multilevel Blocking Monte Carlo simulations
R. Egger, C. H. Mak
This article gives an introduction to the multilevel blocking (MLB) approach to both the fermion and the dynamical sign problem in path-integral Monte Carlo simulations. MLB is abl…

Stabilizing dynamical localization in driven tunneling
J. Stockburger, C. H. Mak
Dynamical localization of a tunneling system by means of an oscillating external field is examined for an arbitrary doublet of tunneling states. We show that the condition of an ex…
