Physical Review A - Atomic, Molecular, and Optical Physics, 85(3), Article 032506. https://doi.org/10.1103/physreva.85.032506

We have studied interspecies scattering in an ultracold mixture of 87Rb and 133Cs atoms, both in their lowest-energy spin states. The three-body loss signatures of 30 incoming s- and p-wave magnetic Feshbach resonances over the range 0 to 667 G have...

Magnetically Tunable Feshbach Resonances in Ultracold Li-Yb Mixtures (2012)
Journal Article

We investigate the possibility of forming Li+Yb ultracold molecules by magnetoassociation in mixtures of ultracold atoms. We find that magnetically tunable Feshbach resonances exist, but are extremely narrow for even-mass ytterbium isotopes, which al...

Optimized multichannel quantum defect theory for cold molecular collisions (2012)
Journal Article
Croft, J. F., Hutson, J. M., & Julienne, P. S. (2012). Optimized multichannel quantum defect theory for cold molecular collisions. Physical Review A, 86(2), Article 022711. https://doi.org/10.1103/physreva.86.022711

Multichannel quantum defect theory (MQDT) can provide an efficient alternative to full coupled-channel calculations for low-energy molecular collisions. However, the efficiency relies on interpolation of the Y matrix that encapsulates the short-range... Read More about Optimized multichannel quantum defect theory for cold molecular collisions.
