Bose-Einstein condensation in the canonical ensemble
arXiv:hep-ph/0308067 · doi:10.1103/PhysRevD.68.105007
Abstract
Large-volume, high-temperature Bose-Einstein condensation is illustrated for a relativistic O(2)-invariant scalar field with fixed charge using the canonical ensemble. The standard, grand canonical results are reproduced for the infinite-volume limit. Finite-volume corrections are calculated in the canonical ensemble and the results are found to differ from the finite-volume grand canonical approximation in a consistent qualitative way.
