Quantum reflection and localization in bound systems — •Elias Diesen1 and Jan-Michael Rost2 — 1Max-Planck-Institut für Physik komplexer Systeme — 2Max-Planck-Institut für Physik komplexer Systeme
The phenomenon of quantum reflection is briefly presented and compared to the situation where a similar shape of the underlying potential causes localization of eigenstates in a confining potential. The relation of both these quantum phenomena to the breakdown of semiclassical (WKB) dynamics is discussed. A few physical systems that show such behaviour are presented, among them the ultracold Rydberg dimer, consisting of a ground state and a Rydberg atom [1]. Due to the current rapid development of experimental techniques for the ultracold regime, these phenomena should become more and more accessible to direct experimental investigation.
