Quantum Optics and Quantum Mechanics of Time
Contact Person: Andreas Ruschhaupt
One research goal is the theoretical development of new and the improvement of existing laser-based devices to prepare and control single-atom and many-atom internal and translational states. Especially, this includes applications and improvements of the atom diode (a laser-based device that lets the atom pass solely in one direction) and devices for velocity selection.
Another research goal is to discover quantum time effects, i.e. effects arising from a quantum-mechanical treatment of time observables. We are examining the influence of a quantum description of the photonic arrival time in quantum communication schemes and the arrival time of massive particles.
