Phys. Rev. A 68, 043816 (2003) [15 pages]Electromagnetic-field quantization and spontaneous decay in left-handed mediaReceived 4 June 2003; published 13 October 2003 We present a quantization scheme for the electromagnetic field interacting with atomic systems in the presence of dispersing and absorbing magnetodielectric media, including left-handed material having negative real part of the refractive index. The theory is applied to the spontaneous decay of a two-level atom at the center of a spherical free-space cavity surrounded by magnetodielectric matter of overlapping band-gap zones. Results for both big and small cavities are presented, and the problem of local-field corrections within the real-cavity model is addressed. © 2003 The American Physical Society URL:
