Ultracold gas of ground-state polar KRb molecules in 2D

POSTER

Abstract

We report on our ongoing studies of dipolar interactions in ground-state KRb molecules prepared in the quantum regime. At large dipole moment we see a dramatic increase in the inelastic scattering rate due to attractive head-to-tail interactions between molecules [1]. To suppress this inelastic loss we are preparing a gas of polar molecules in a 2D confined geometry provided by a one-dimensional optical lattice. We will explore the effect of the 2D confinement on the lifetime of the trapped molecule gas. \\[4pt] [1] K.-K. Ni, S. Ospelkaus, D. Wang, G. Quemener, B. Neyenhuis, M. H. G. de Miranda, J. L.
