Phys. Rev. A 72, 022104 (2005) [6 pages]Microscopic theory of spontaneous decay in a dielectricReceived 13 April 2005; published 9 August 2005 The local field correction to the spontanous decay rate of an impurity source atom embedded in a disordered dielectric is calculated to second order in the dielectric density. The result is found to differ from predictions associated with both “virtual” and “real” cavity models of this decay process. However, if the contributions from two dielectric atoms at the same position are included, the virtual cavity result is reproduced. © 2005 The American Physical Society URL:
