Trapping and cooling mechanisms in blue-detuned magneto-optical traps of molecules
Qinshu Lyu, M. R. Tarbutt
In red-detuned magneto-optical traps (MOTs) of molecules, sub-Doppler heating competes with Doppler cooling, resulting in high temperature and low density. A solution is offered by…

Etienne F. Walraven, Michael R. Tarbutt, Tijs Karman
We propose to repeatedly load laser-cooled molecules into optical tweezers, and transfer them to storage states that are rotationally excited by two additional quanta. Collisional…
