Interference scheme to measure light-induced nonlinearities in Bose-Einstein condensates
K. V. Krutitsky, K. -P. Marzlin, J. Audretsch
Light-induced nonlinear terms in the Gross-Pitaevskii equation arise from the stimulated coherent exchange of photons between two atoms. For atoms in an optical dipole trap this ef…
States insensitive to the Unruh effect in multi-level detectors
Karl-Peter Marzlin, J"urgen Audretsch
We give a general treatment of the spontaneous excitation rates and the non-relativistic Lamb shift of constantly accelerated multi-level atoms as a model for multi-level detectors…
Continuous Fuzzy Measurement of Energy for a Two-Level System
Jürgen Audretsch, Michael Mensky
A continuous measurement of energy which is sharp (perfect) leads to the quantum Zeno effect (freezing of the state). Only if the quantum measurement is fuzzy, continuous monitorin…
Actio causes reactio: Gravito-optical trapping of three-level atoms
Karl-Peter Marzlin, Jürgen Audretsch
We investigate an atomic three-level -system which is exposed to two counterpropagating laser fields (inducing Raman transitions) and which is closed by a magnetic hyperfine fie…
Topological Defects in Gravitational Theories with Non Linear Lagrangians
J. Audretsch, A. Economou, C. O. Lousto
The gravitational field of monopoles, cosmic strings and domain walls is studied in the quadratic gravitational theory with , and is compared with the result in…
