Unified approach to QED in arbitrary linear media
Christian Raabe, Stefan Scheel, Dirk-Gunnar Welsch
We give a unified approach to macroscopic QED in arbitrary linearly responding media, based on the quite general, nonlocal form of the conductivity tensor as it can be introduced w…
Local-field correction to one- and two-atom van der Waals interactions
Agnes Sambale, Stefan Yoshi Buhmann, Dirk-Gunnar Welsch +1
Based on macroscopic quantum electrodynamics in linearly and causally responding media, we study the local-field corrected van der Waals potentials and forces for unpolarized groun…
Characterization of unwanted noise in realistic cavities
A. A. Semenov, D. Yu. Vasylyev, W. Vogel +2
The problem of the description of absorption and scattering losses in high-Q cavities is studied. The considerations are based on quantum noise theories, hence the unwanted noise a…
Determination of quantum-noise parameters of realistic cavities
A. A. Semenov, W. Vogel, M. Khanbekyan +1
A procedure is developed which allows one to measure all the parameters occurring in a complete model [A.A. Semenov et al., Phys. Rev. A 74, 033803 (2006); quant-ph/0603043] of rea…
Dispersion forces in macroscopic quantum electrodynamics
Stefan Yoshi Buhmann, Dirk-Gunnar Welsch
The description of dispersion forces within the framework of macroscopic quantum electrodynamics in linear, dispersing, and absorbing media combines the benefits of approaches base…
Body-assisted van der Waals interaction between two atoms
Hassan Safari, Stefan Yoshi Buhmann, Dirk-Gunnar Welsch +1
Using fourth-order perturbation theory, a general formula for the van der Waals potential of two neutral, unpolarized, ground-state atoms in the presence of an arbitrary arrangemen…
