Characterization of the lowest excited-state ro-vibrational level of $^{23}$Na$^{87}$Rb

  title={Characterization of the lowest excited-state ro-vibrational level of \$^\{23\}\$Na\$^\{87\}\$Rb},
  author={Junyu He and Junyu Lin and Romain Vexiau and Nadia Bouloufa and Olivier Dulieu and Dajun Wang},
Starting from an ultracold sample of ground-state NaRb molecules, we investigate the lowest ro-vibrational level of the bΠ state with high resolution laser spectroscopy. This electronic spinforbidden XΣ ↔ bΠ transition features a nearly diagonal Franck-Condon factor and has been proposed useful for probing and manipulating the ultracold molecular gas. We measure the transition strength directly by probing the ac Stark shift induced by near resonance light and determine the total excited-state… Expand

A sample of over 1000 ultracold ^{87}Rb^{133}Cs molecules in the lowest rovibrational ground state is created by magnetoassociation on an interspecies Feshbach resonance followed by stimulated Raman adiabatic passage (STIRAP). Expand
Ultracold Gas of Bosonic ^{23}Na^{39}K Ground-State Molecules.
The creation of ultracold bosonic dipolar ^{23}Na^{39}K molecules in their absolute rovibrational ground state is reported and an unexpectedly low two-body decay coefficient for collisions between molecules and ^{39]K atoms in a selected hyperfine state is found. Expand
Nuclear spin conservation enables state-to-state control of ultracold molecular reactions
By manipulating the reactants’ nuclear spins using an external magnetic field, control over the product state distribution of a bimolecular reaction has been demonstrated and opens up the possibilities to study quantum entanglement between reaction products and ultracold reaction dynamics at the state-to-state level.

A High Phase-Space-Density Gas of Polar Molecules
An ultracold dense gas of potassium-rubidium (40K87Rb) polar molecules is created using a single step of STIRAP with two-frequency laser irradiation to coherently transfer extremely weakly bound KRb molecules to the rovibrational ground state of either the triplet or the singlet electronic ground molecular potential.
