Monte-Carlo simulation for the frequency comb spectrum of an atom laser
A. Schelle
A theoretical particle-number conserving quantum field theory based on the concept of imaginary time is presented and applied to the scenario of a coherent atomic laser field at ul…
Transition of a mesoscopic bosonic gas into a Bose-Einstein condensate
Alexej Schelle
The condensate number distribution during the transition of a dilute, weakly interacting gas of N=200 bosonic atoms into a Bose-Einstein condensate is modeled within number conserv…
Number-conserving master equation theory for a dilute Bose-Einstein condensate
Alexej Schelle, Thomas Wellens, Dominique Delande +1
We describe the transition of weakly interacting atoms into a Bose-Einstein condensate within a number-conserving quantum master equation theory. Based on the separation of tim…
Microwave-Driven Atoms: From Anderson Localization to Einstein's Photoeffect
Alexej Schelle, Dominique Delande, Andreas Buchleitner
We study the counterpart of Anderson localization in driven one-electron Rydberg atoms. By changing the initial Rydberg state at fixed microwave frequency and interaction time, we…
