Phys. Rev. Lett. 105, 073202 (2010) [4 pages]Universal Rates for Reactive Ultracold Polar Molecules in Reduced DimensionsReceived 30 April 2010; published 13 August 2010 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 trapping strength, whereas bosons or unlike fermions require significantly higher dipole or trapping strengths. © 2010 The American Physical Society URL:
