Kt. Kapale et Ms. Zubairy, Equivalence of the master equation approach to the canonical ensemble approach for an ideal Bose gas, OPT COMMUN, 191(3-6), 2001, pp. 299-304
A picture of the condensate statistics of a confined Bose gas, which is mor
e relevant to recent experimental realizations, can be obtained by the cano
nical ensemble approach. Nevertheless, handling the particle number conserv
ation condition entering therein is a formidable task. A recent method deve
loped to deal with this problem is a non-equilibrium master equation approa
ch based on the quantum theory of laser. We show here how the equilibrium s
olution of this master equation is faithful to the canonical ensemble. (C)
