The Effective Action at Finite Temperature and Density With Application to Bose-Einstein Condensation
David J. Toms
A simple pedagogical introduction to the effective action method of quantum field theory is given at a level suitable for beginning postgraduate students. It is shown how to obtain…
Density of states for Bose-Einstein condensation in harmonic oscillator potentials
Klaus Kirsten, David J. Toms
We discuss how it is possible to obtain a reliable approximation for the density of states for a system of particles in an anisotropic harmonic oscillator potential. A direct appli…
Bose-Einstein condensation of atomic gases in a general harmonic oscillator
Klaus Kirsten, David J. Toms
We present an analysis of Bose-Einstein condensation for a system of non-interacting spin-0 particles in a harmonic oscillator confining potential trap. We discuss why a confined s…
Bose-Einstein condensation of atomic gases in a harmonic oscillator confining potential trap
Klaus Kirsten, David J. Toms
We present a model which predicts the temperature of Bose-Einstein condensation in atomic alkali gases and find excellent agreement with recent experimental observations. A system…
Bose-Einstein condensation as symmetry breaking in compact curved spacetimes
John D. Smith, David J. Toms
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…
