Universal Rates for Reactive Ultracold Polar Molecules in Reduced Dimensions

Universal Rates for Reactive Ultracold Polar Molecules in Reduced Dimensions

Analytic expressions describe universal elastic and reactive rates of quasi-two-dimensional and quasi-one-dimensional collisions of highly reactive ultracold molecules interacting by a van der Waals potential. Exact and approximate calculations for the example species KRb show that stability and evaporative cooling can be realized for spin-polarized fermions at moderate dipole and …
