Photon emission by an atom in a lossy cavity
C. Di Fidio, W. Vogel, M. Khanbekyan +1
The dynamics of an initially excited two-level atom in a lossy cavity is studied by using the quantum trajectory method. Unwanted losses are included, such as photon absorption and…
Van der Waals interaction and spontaneous decay of an excited atom in a superlens-type geometry
Agnes Sambale, Stefan Yoshi Buhmann, Dirk-Gunnar Welsch +1
Within the framework of macroscopic quantum electrodynamics, the resonant van der Waals potential experienced by an excited two-level atom near a planar magneto-electric two-layer…
Cavity-assisted spontaneous emission as a single-photon source: Pulse shape and efficiency of one-photon Fock state preparation
M. Khanbekyan, D. -G. Welsch, C. Di Fidio +1
Within the framework of exact quantum electrodynamics in dispersing and absorbing media, we have studied the quantum state of the radiation emitted from an initially in the upper s…
QED in arbitrary linear media: amplifying media
Christian Raabe, Dirk-Gunnar Welsch
Recently, we have developed a unified approach to QED in arbitrary linearly responding media in equilibrium--media that give rise to absorption [Phys. Rev. A \textbf{75}, (2007) 05…
Casimir-Polder forces on excited atoms in the strong atom-field coupling regime
Stefan Yoshi Buhmann, Dirk-Gunnar Welsch
Based on macroscopic quantum electrodynamics in linear media, we develop a general theory of the resonant Casimir-Polder force on an excited two-level atom in the presence of arbit…
