Abstract
We demonstrate suppression of the reactive loss in a gas of ultracold 40K87Rb molecules in a three-dimensional geometry. The electric field-induced collisional shielding suppresses loss by two orders of magnitude while preserving elastic, long-range dipolar interactions. The favorable ratio of elastic to inelastic collisions enables direct thermalization manifested via cross-dimensional thermal relaxation. The rate of the relaxation depends on the angle between the collisional axis and the dipole orientation, a characteristic of anisotropic dipolar interactions. This work establishes a longlived bulk quantum gas system with tunable interactions, paving the way for the study of collective quantum many-body physics mediated by long-range interactions.Citation
