Condensation and interaction range in harmonic boson traps: a variational approach
J. Tempere, F. Brosens, L. F. Lemmens +1
For a gas of N bosons interacting through a two-body Morse potential a variational bound of the free energy of a confined system is obtained. The calculation method is based on the…
Rotational properties of trapped bosons
F. Brosens, J. T. Devreese, L. F. Lemmens
Based on the Hellman-Feynman theorem it is shown that the average square radius of a cloud of interacting bosons in a parabolic well can be derived from their free energy. As an ap…
Thermodynamics of Coupled Identical Oscillators within the Path Integral Formalism
F. Brosens, J. T. Devreese, L. F. Lemmens
A generalization of symmetrized density matrices in combination with the technique of generating functions allows to calculate the partition function of identical particles in a pa…
Many-Body Diffusion and Path Integrals for Identical Particles
L. F. Lemmens, F. Brosens, J. T. Devreese
For distinguishable particles it is well known that Brownian motion and a Feynman-Kac functional can be used to calculate the path integral (for imaginary times) for a general clas…
