One-Dimensional Rydberg Gas in a Magnetoelectric Trap — •Bernd Hezel¹, Michael Mayle², Igor Lesanovsky³, and Peter Schmelcher^1,2 — 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.
