Resonance collisions of ultracold polar molecules in a microwave field

А. V. Avdeenkov

The collisions at ultracold temperatures between 1Σ state diatomic polar molecules in a microwave field with a circular polarization are theoretically analyzed. We demonstrate the possibility of trapping polar molecules in the standing-wave electromagnetic field and a successful evaporative cooling not only for samples of molecules in their absolute ground states but in some rotationally excited states in the appropriate regions of frequencies of a field. Here we only discuss fermionic polar molecules at ultralow temperatures(1μK), considering RbK as a prototype.The collisions at ultracold temperatures between 1Σ state diatomic polar molecules in a microwave field with a circular polarization are theoretically analyzed.

Optical production of ultracold polar molecules

David P. DeMille, Jeremy Sage, S. Sainis +1 more

We present recent work resulting in the production of ultracold, polar RbCs molecules in their absolute vibronic ground state. The production process consists of several steps: photoassociation of laser‐cooled atoms; radiative stabilization of the resulting molecules; identification of the resulting population distribution; and laser‐stimulated stale transfer lo the vibrational ground state. We discuss the properties of the resulting sample of of X1Σ+(ν = 0) molecules, with a view to the future directions of these experiments.We present recent work resulting in the production of ultracold, polar RbCs molecules in their absolute vibronic ground state.
