Comment on ``Critical temperature of trapped hard-sphere Bose gases''
Werner Krauth
In this comment, I discuss a recent path-integral Monte Carlo calculation by Pearson, Pang, and Chen (Phys. Rev. A 58, 4796 (1998)). For bosons with a small hard-core interaction i…
Phase Separation in Two-Dimensional Additive Mixture
Arnaud Buhot, Werner Krauth
We study 2-dimensional binary mixtures of parallel squares as well as of disks. A recent cluster algorithm allows us to establish an entropic demixing transition between a homogene…
Precision Monte Carlo Test of the Hartree-Fock Approximation for a trapped Bose Gas
Markus Holzmann, Werner Krauth, Martin Naraschewski
We compare the semiclassical Hartree-Fock approximation for a trapped Bose gas to a direct Path Integral Quantum Monte Carlo simulation. The chosen parameters correspond to current…
Finite Yang-Mills Integrals
Werner Krauth, Matthias Staudacher
We use Monte Carlo methods to directly evaluate D-dimensional SU(N) Yang-Mills partition functions reduced to zero Euclidean dimensions, with and without supersymmetry. In the non-…
Monte Carlo Approach to M-Theory
Werner Krauth, Hermann Nicolai, Matthias Staudacher
We discuss supersymmetric Yang-Mills theory dimensionally reduced to zero dimensions and evaluate the SU(2) and SU(3) partition functions by Monte Carlo methods. The exactly known…
