Microwave shielding of ultracold polar molecules with imperfectly circular polarization

Karman, Tijs; Hutson, Jeremy M.

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.
