摘　　要：We investigate the decay rate of an atom in a two-dimensional optical microcavity in which there exists a BoseEinstein condensation of photons.It is found that below the critical temperature To,the atomic decay rate depends on the absolute temperature T.Especially,at absolute zero temperature almost all photons are in the condensate state,and the atom can be approximately treated as if it is in vacuum.
