Manipulation of a quantum particle in a rapidly oscillating potential by phase hops — Armin Ridinger¹ and •Christoph Weiss^1,2 — ¹Laboratoire Kastler Brossel, École Normale Supérieure, Université Pierre et Marie-Curie-Paris 6, CNRS — ²Institut für Physik, Universität Oldenburg

We show that the state and the energy of a quantum particle trapped by a rapidly oscillating potential can be significantly manipulated in a controlled fashion by instantaneously changing the phase of the potential (a phase hop). We demonstrate our results for the case of the ideal one-dimensional Paul-trap.
