Probing reflectionless potentials via atomic dynamics — •Martin Lahrz and Ludwig Mathey — University of Hamburg, Hamburg, Germany

We explore how reflectionless potentials can be probed via atomic dynamics. If a quantum mechanical wave package passes through a potential, ordinarily, a finite fraction of it gets reflected. However, in special cases, e.g. for specific Pöschl-Teller potentials, the reflection is zero and the full object is transmitted. We investigate the influence of the reflectionless potential on the outgoing wave function and compare it with the propagation of the free particle. This scenario might be realized in an ultra-cold atom system where the potential is represented by an optical trap.
