  title = {Blue-Detuned Magneto-optical Trap of Molecules},
  abstract = {<p>Direct laser cooling of molecules has reached a phase-space density exceeding 10<sup>−6</sup> in optical traps but<br />
with rather small molecular numbers. To progress toward quantum degeneracy, a mechanism that combines<br />
sub-Doppler cooling and magneto-optical trapping would facilitate near unity transfer of ultracold<br />
molecules from the magneto-optical trap (MOT) to a conservative optical trap. Using the unique energy<br />
level structure of YO molecules, we demonstrate the first blue-detuned MOT for molecules that is<br />
optimized for both gray-molasses sub-Doppler cooling and relatively strong trapping forces. This first sub-<br />
Doppler molecular MOT provides an increase of phase-space density by 2 orders of magnitude over any<br />
previously reported molecular MOT.</p>
