We demonstrate coherent control of the rotational and hyperfine state of ultracold, chemically stable Rb87Cs133 molecules with external microwave fields. We create a sample of ∼2000 molecules in the lowest hyperfine level of the rovibronic ground sta... Read More about Controlling the rotational and hyperfine state of ultracold Rb87Cs133 molecules.

We present the production of ultracold 87 RbCs molecules in the electronic, rovibrational and hyperfine ground state, using stimulated Raman adiabatic passage to transfer the molecules from a weakly bound Feshbach state. We measure one-way transfer e... Read More about Production of ultracold 87Rb133Cs in the absolute ground state: complete characterisation of the STIRAP transfer.

We investigate Born-Oppenheimer breakdown (BOB) effects (beyond the usual mass scaling) for the electronic ground states of a series of homonuclear and heteronuclear alkali-metal diatoms, together with the Sr2 and Yb2 diatomics. Several widely availa... Read More about Deviations from Born-Oppenheimer mass scaling in spectroscopy and ultracold molecular physics.

Creating Feshbach resonances for ultracold molecule formation with radio-frequency fields (2016)
Journal Article

We show that radio-frequency (rf) radiation may be used to create Feshbach resonances in ultracold gases of alkali-metal atoms at desired magnetic fields that are convenient for atomic cooling and degeneracy. For the case of K39+Cs133, where there ar... Read More about Creating Feshbach resonances for ultracold molecule formation with radio-frequency fields.

Approach to chaos in ultracold atomic and molecular physics: Statistics of near-threshold bound states for Li+CaH and Li+CaF (2016)

We calculate near-threshold bound states and Feshbach resonance positions for atom–rigid-rotor models of the highly anisotropic systems Li+CaH and Li+CaF. We perform statistical analysis on the resonance positions to compare with the predictions of r...

We calculate and analyze Feshbach resonance spectra for ultracold Yb(1S0)+Yb(3P2) collisions as a function of an interatomic potential scaling factor λ and external magnetic field.
