Entanglement in a Raman-driven cascaded system
C. Di Fidio, W. Vogel
The dynamics of a cascaded system that consists of two atom-cavity subsystems is studied by using the quantum trajectory method. Considering the two atom-cavity subsystems driven b…
Experimental determination of a nonclassical Glauber-Sudarshan P function
T. Kiesel, W. Vogel, V. Parigi +2
A quantum state is nonclassical if its Glauber-Sudarshan P function fails to be interpreted as a probability density. This quantity is often highly singular, so that its reconstruc…
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…
Robust "trapping states" in the motion of a trapped ion
S. Wallentowitz, W. Vogel, P. E. Toschek
A novel robust mechanism for the generation of "trapping states" is shown to exist in the coupling of a two-level system with an oscillator, which is based on nonlinearities in the…
Casimir-Polder interaction of atoms with magnetodielectric bodies
Stefan Yoshi Buhmann, Ho Trung Dung, Thomas Kampf +1
A general theory of the Casimir-Polder interaction of single atoms with dispersing and absorbing magnetodielectric bodies is presented, which is based on QED in linear, causal medi…
Quantum Limits of Stochastic Cooling of a Bosonic Gas
D. Ivanov, S. Wallentowitz, I. A. Walmsley
The quantum limits of stochastic cooling of trapped atoms are studied. The energy subtraction due to the applied feedback is shown to contain an additional noise term due to atom-n…
