Comment on: 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…

The Partition Function of a Spinor Gas
L. F. Lemmens, F. Brosens, J. T. Devreese
For a spinor gas, i.e., a mixture of identical particles with several internal degrees of freedom, we derive the partition function in terms of the Feynman-Kac functionals of polar…
