Microwave shielding of ultracold polar molecules with imperfectly circular polarization.

Karman, Tijs and Hutson, Jeremy M. (2019) 'Microwave shielding of ultracold polar molecules with imperfectly circular polarization.', Physical review A, 100 (5). 052704.

Abstract

We investigate the use of microwave radiation to produce a repulsive shield between pairs of ultracold polar molecules and prevent collisional losses that occur when molecular pairs reach short range. We carry out coupledchannels calculations on RbCs + RbCs and CaF + CaF collisions in microwave fields. We show that effective shielding requires predominantly circular polarization but can still be achieved with elliptical polarization that is around 90% circular.
