Mapping the composite character of magnetically trapped Rydberg atoms — •Michael Mayle1, Igor Lesanovsky2, and Peter Schmelcher1,31Theoretische Chemie, Universität Heidelberg — 2School of Physics and Astronomy, University of Nottingham, UK — 3Physikalisches Institut, Universität Heidelberg

By investigating the quantum properties of magnetically trapped nS1/2 Rydberg atoms, it is demonstrated that the composite nature of Rydberg atoms significantly alters their trapping properties opposed to point-like particles with identical magnetic moment. Employing an off-resonant two photon coupling scheme, a setup is proposed which allows to observe the signatures of the Rydberg trapping potential using a gas of ground state atoms. In addition, such a scheme provides new possibilities for designing trapping potentials for ground state atoms.
