Inference from Iterative Simulation Using Multiple Sequences
(Institute of Mathematical Statistics, 1992)The Gibbs sampler, the algorithm of Metropolis and similar iterative simulation methods are potentially very helpful for summarizing multivariate distributions. Used naively, however, iterative simulation can give misleading ... -
Path Integral Monte Carlo with Importance Sampling for Excitons Interacting with an Arbitrary Phonon Bath
(American Institute of Physics, 2012)The reduced density matrix of excitons coupled to a phonon bath at a finite temperature is studied using the path integral Monte Carlo method. Appropriate choices of estimators and importance sampling schemes are crucial ...
