External field control of spin-dependent rotational decoherence of ultracold polar molecules
External field control of spin-dependent rotational decoherence of ultracold polar molecules
We determine trapping conditions for ultracold polar molecules, where pairs of internal states experience identical trapping potentials. Such conditions could ensure that detrimental effects of inevitable inhomogeneities across an ultracold sample are significantly reduced. In particular, we investigate the internal rovibronic and hyperfine quantum states of ultracold fermionic ground-state 40K87Rb …
