Spontaneous emission from an atom in motion near an infinite conducting plane

We evaluate the probability of (de)excitation and photon emission from a neutral, moving, nonrelativistic atom, coupled to the quantum electromagnetic field and in the presence of a thin, perfectly conducting plane (``mirror''). These results extend, to a more realistic model, the ones we had presented for a scalar model, where the would-be electron was described by a scalar variable, coupled to an (also scalar) vacuum field. The latter was subjected to either Dirichlet or Neumann conditions on a plane. In our evaluation of the spontaneous emission rate produced when the accelerated atom is initially in an excited state, we pay attention to its comparison with the somewhat opposite situation, namely, an atom at rest facing a moving mirror.

We compute the influence on the spontaneous-emission rate for a two-level atom when it is located between two parallel plates of a different nature, namely a perfectly conducting plate $(\stackrel{\ensuremath{\rightarrow}}{\ensuremath{\epsilon}}\ensuremath{\infty})$ and an infinitely permeable one $(\stackrel{\ensuremath{\rightarrow}}{\ensuremath{\mu}}\ensuremath{\infty}).$ We also discuss the case of two infinitely permeable plates. We compare our results with those found in the literature for the case of two perfectly conducting plates.
