Instability in a Two-Dimensional Dilute Interacting Bose System
W. J. Mullin, M. Holzmann, F. Laloe
The formalism of Ursell operators provides a self-consistent integral equation for the one-particle reduced operator. In three dimensions this technique yields values of the shift…
Validity of the Hohenberg Theorem for a Generalized Bose-Einstein Condensation in Two Dimensions
W. J. Mullin, M. Holzmann, F. Laloe
Several authors have considered the possibility of a generalized Bose-Einstein condensation (BEC) in which a band of low states is occupied so that the total occupation number is m…
Quantum-Monte-Carlo Calculations for Bosons in a Two-Dimensional Harmonic Trap
Stefan Heinrichs, William J. Mullin
Path-Integral-Monte-Carlo simulation has been used to calculate the properties of a two-dimensional (2D) interacting Bose system. The bosons interact with hard-core potentials and…
A Study of Bose-Einstein Condensation in a Two-Dimensional Trapped Gas
William J. Mullin
We examine the possibility of Bose-Einstein condensation (BEC) in two-dimensional (2D) system of interacting particles in a trap. We use a self-consistent mean-field theory of Bose…
