Minimal Autocorrelation in Hybrid Monte Carlo simulations using Exact Fourier Acceleration
Johann Ostmeyer, Pavel Buividovich
The hybrid Monte Carlo (HMC) algorithm is a ubiquitous method in computational physics with applications ranging from condensed matter to lattice QCD and beyond. However, HMC simul…

High-precision Quantum Monte-Carlo study of charge transport in a lattice model of molecular organic semiconductors
Pavel Buividovich, Johann Ostmeyer, Alessandro Troisi
We use first-principle Quantum Monte-Carlo (QMC) simulations and numerical exact diagonalization to analyze the low-frequency charge carrier mobility within a simple tight-binding…

Out-of-equilibrium Chiral Magnetic Effect from simulations on Euclidean lattices
P. V. Buividovich
The status of the Chiral Magnetic Effect (CME) response in full Quantum Chromodynamics (QCD) has been controversial so far, with previous lattice QCD studies indicating either its…
