Mapping the composite character of magnetically trapped Rydberg atoms — •Michael Mayle¹, Igor Lesanovsky², and Peter Schmelcher^1,3 — ¹Theoretische Chemie, Universität Heidelberg — ²School of Physics and Astronomy, University of Nottingham, UK — ³Physikalisches Institut, Universität Heidelberg

By investigating the quantum properties of magnetically trapped nS_1/2 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.
