    "abstract": "We consider the interaction of atoms with the quantized electromagnetic field\nin the presence of materials with negative index of refraction. Spontaneous\nemission of an atom embedded in a negative index material is discussed. It is\nshown furthermore that the possibility of a vanishing optical path length\nbetween two spatially separated points provided by these materials can lead to\ncomplete suppression of spontaneous emission of an atom in front of a perfect\nmirror even if the distance between atom and mirror is large compared to the\ntransition wavelength. Two atoms put in the focal points of a lens formed by a\nparallel slab of ideal negative index material are shown to exhibit perfect\nsub- and superradiance. The maximum length scale in both cases is limited only\nby the propagation distance within the free-space radiative decay time.\nLimitations of the predicted effects arising from absorption, finite\ntransversal extension and dispersion of the material are analyzed.",
