Critical temperature of a Bose gas in an optical lattice
arXiv:0905.4783 · doi:10.1103/PhysRevA.80.031603
Abstract
We present theory for the critical temperature of a Bose gas in a combined harmonic lattice potential based on a mean-field description of the system. We develop practical expressions for the ideal-gas critical temperature, and corrections due to interactions, the finite-size effect, and the occupation of excited bands. We compare our expressions to numerical calculations and find excellent agreement over a wide parameter regime.
