Mapping the dipole-dipole interaction among ultracold Rydberg atoms
ORAL
Abstract
A long-range dipole-dipole interaction couples the atoms in an ultracold Rydberg gas. This can lead to changes in the spatial configuration of states over an extended region. We discuss the use of selective field ionization with a spatially sensitive ion detector to directly map dipole-dipole interaction induced level shifts and energy exchange over large distances in a MOT. Experimental and simulation results will be presented.
