Exchange Monte Carlo for continuous-space Path Integral Monte Carlo simulation (opens in new tab)

arXiv:2602.05500v1 Announce Type: new Abstract: We present a novel Exchange Monte Carlo (EMC) method designed for application in continuous-space Path Integral Monte Carlo (PIMC) simulations at finite temperature. Traditional PIMC methods for bosonic systems suffer from long autocorrelation times, particularly when measuring observables affected by particle permutations, such as the winding number. To address this issue, we introduce an exchange update scheme that facilitates replica transit...
