Momentum distribution of confined bosons: temperature dependence
J. Tempere, F. Brosens, L. F. Lemmens +1
The momentum distribution function of a parabolically confined gas of bosons with harmonic interparticle interactions is derived. In the Bose-Einstein condensation region, this mom…
Correlations in a Confined gas of Harmonically Interacting Spin-Polarized Fermions
F. Brosens, J. T. Devreese, L. F. Lemmens
For a fermion gas with equally spaced energy levels, the density and the pair correlation function are obtained. The derivation is based on the path integral approach for identical…
Switching Boundary Conditions in the Many-Body Diffusion Algorithm
F. Luczak, F. Brosens, J. T. Devreese +1
In this paper we show how the transposition, the basic operation of the permutation group, can be taken into account in a diffusion process of identical particles. Whereas in an ea…
Statistical mechanics and path integrals for a finite number of bosons
L. F. Lemmens, F. Brosens, J. T. Devreese
Recent investigations show that the statistical mechanics of a finite number of particles in ideal harmonic systems predicts different results for the same physical properties, dep…
Large Bipolaron in a Polaron-Gas Background
M. A. Smondyrev, A. A. Shanenko, J. T. Devreese
A criterion, proposed by the present authors, is used to derive numerical results for the stability of a large bipolaron embedded in a polaron gas. The main conclusion is that an i…
