Microwave shielding of ultracold polar molecules.

Karman, Tijs and Hutson, Jeremy M. (2018) 'Microwave shielding of ultracold polar molecules.', Physical review letters., 121 (16). p. 163401.

Abstract

We use microwaves to engineer repulsive long-range interactions between ultracold polar molecules. The resulting shielding suppresses various loss mechanisms and provides large elastic cross sections. Hyperfine interactions limit the shielding under realistic conditions, but a magnetic field allows suppression of the losses to below 10 − 14     cm 3   s − 1 . The mechanism and optimum conditions for shielding differ substantially from those proposed by Gorshkov et al. [Phys. Rev. Lett. 101, 073201 (2008)], and do not require cancellation of the long-range dipole-dipole interaction that is vital to many applications.
