One-Dimensional Rydberg Gas in a Magnetoelectric Trap — •Bernd Hezel1, Michael Mayle2, Igor Lesanovsky3, and Peter Schmelcher1,2 — 1Physikalisches Institut, Universität Heidelberg, 69120 Heidelberg, Germany — 2Theoretische Chemie, Universität Heidelberg, 69120 Heidelberg, Germany — 3Institut für Theoretische Physik, Universität Innsbruck, 6020 Innsbruck, Austria
We study the quantum properties of Rydberg atoms in a magnetic Ioffe-Pritchard trap superimposed by a homogeneous electric field. Trapped Rydberg atoms in long-lived electronic states can be created with permanent electric dipole moments of several hundred Debye. The resulting dipole-dipole interaction in conjunction with the radial confinement gives rise to an effectively one-dimensional ultracold Rydberg gas with a macroscopic interparticle distance. Analytical expressions for the electric dipole moment and the required linear density of Rydberg atoms can be derived.
