Bose-Einstein Condensation on Product Manifolds
We investigate the phenomenon of Bose-Einstein condensation on manifolds
constructed as a product of a three-dimensional Euclidian space and a general
smooth, compact -dimensional manifold possibly with boundary. By using
spectral -function methods, we are able to explicitly provide
thermodynamical quantities like the critical temperature and the specific heat
when the gas of bosons is confined, in the three-dimensional manifold, by the
experimentally relevant anisotropic harmonic oscillator potential.Comment: 9 pages, LaTe
Zero modes, entropy bounds and partition functions
Some recent finite temperature calculations arising in the investigation of
the Verlinde-Cardy relation are re-analysed. Some remarks are also made about
temperature inversion symmetry.Comment: 12 pages, JyTe
Bose-Einstein condensation as symmetry breaking in compact curved spacetimes
We examine Bose-Einstein condensation as a form of symmetry breaking in the
specific model of the Einstein static universe. We show that symmetry breaking
never occursin the sense that the chemical potential never reaches its
critical value.This leads us to some statements about spaces of finite volume
in general. In an appendix we clarify the relationship between the standard
statistical mechanical approaches and the field theory method using zeta
functions.Comment: Revtex, 25 pages, 3 figures, uses EPSF.sty. To be published in Phys.
