Ursell operators in statistical physics of dense systems: the role of high order operators and of exchange cycles
J. N. Fuchs, M. Holzmann, F. Laloe
The purpose of this article is to discuss cluster expansions in dense quantum systems as well as their interconnection with exchange cycles. We show in general how the Ursell opera…
Bose-Einstein transition in a dilute interacting gas
Gordon Baym, Jean-Paul Blaizot, Markus Holzmann +2
We study the effects of repulsive interactions on the critical density for the Bose-Einstein transition in a homogeneous dilute gas of bosons. First, we point out that the simple m…
Non-analytic dependence of the transition temperature of the homogeneous dilute Bose gas on scattering length
Markus Holzmann, Gordon Baym, Jean-Paul Blaizot +1
We show that the shift in the transition temperature of the dilute homogeneous Bose gas is non-analytic in the scattering amplitude, . The first correction beyond the positive l…
Pair correlation function of an inhomogeneous interacting Bose-Einstein condensate
M. Holzmann, Y. Castin
We calculate the pair correlation function of an interacting Bose gas in a harmonic trap directly via Path Integral Quantum Monte Carlo simulation for various temperatures and comp…
Bose-Einstein condensation of interacting gases
M. Holzmann, P. Gruter, F. Laloe
We study the occurrence of a Bose-Einstein transition in a dilute gas with repulsive interactions, starting from temperatures above the transition temperature. The formalism, based…
