Optimal Energy Estimation in Path-Integral Monte Carlo Simulations
We investigate the properties of two standard energy estimators used in path-integral Monte Carlo simulations. By disentangling the variance of the estimators and their autocorrelation times we analyse the dependence of the performance on the update algorithm and present a detailed comparison of refined update schemes such as multigrid and staging techniques. We show that a proper combination o...
متن کاملPath Integral Monte Carlo Simulations of Positronium in Argon
Positrons are a useful and non-destructive tool for probing materials; their current uses range from detecting changes in weapons materials [1] to determining whether a diamond is natural or synthetic [2]. Because the positron is the antiparticle of the electron, there are no positrons present in ordinary matter, and it is possible to closely determine what happens to positrons sent into a mate...
متن کاملExtrapolated high-order propagators for path integral Monte Carlo simulations.
We present a new class of high-order imaginary time propagators for path integral Monte Carlo simulations that require no higher order derivatives of the potential nor explicit quadratures of Gaussian trajectories. Higher orders are achieved by an extrapolation of the primitive second-order propagator involving subtractions. By requiring all terms of the extrapolated propagator to have the same...
متن کاملWorm algorithm for continuous-space path integral monte carlo simulations.
We present a new approach to path integral Monte Carlo (PIMC) simulations based on the worm algorithm, originally developed for lattice models and extended here to continuous-space many-body systems. The scheme allows for efficient computation of thermodynamic properties, including winding numbers and off-diagonal correlations, for systems of much greater size than that accessible to convention...
متن کاملPath Integral Monte Carlo Simulations of H 2 Surfaces
The (1,1,1)-surfaces of bulk solid molecular hydrogen have been studied at temperatures between 0.5K and 1.3K, using path integral Monte Carlo. A general method is introduced for constructing an external potential to represent the tail correction for an arbitrary heterogeneous layered bulk substrate-adsorbate system. We compute density pro les parallel and perpendicular to the free H 2 surface,...
