Dressing of Ground State Atoms by Rydberg States in a Ioffe-Pritchard Trap — •Michael Mayle1, Igor Lesanovsky2, and Peter Schmelcher1 — 1Zentrum für Optische Quantentechnologien, Universität Hamburg — 2School of Physics and Astronomy, University of Nottingham, UK
Atomic Rydberg states possess extraordinary properties. Exploiting these qualities is demonstrated to create new handles for the manipulation of ultracold atoms. Taking the external motion of magnetically trapped (Rydberg) atoms as an example, we discuss how the specific features of the Rydberg state can be mapped onto the ground state by means of an off-resonant two-photon laser dressing. In particular, it is demonstrated that the interplay between the spatially varying quantization axis of the considered Ioffe-Pritchard field and the fixed polarization of the laser transition provides a possibility of substantially manipulating the ground state trapping potential.
