Converging on bound states in coupled-channel calculations
C. Ruth Le Sueur, James F. E. Croft, Jeremy M. Hutson
We develop a robust algorithm for locating bound states in coupled-channel calculations. Bound states exist at energies where an individual eigenvalue of a log-derivative or ratio…

Formation of ultracold KCs Feshbach molecules
Charly Beulenkamp, Krzysztof P. Zamarski, Robert C. Bird +4
We report the creation of an ultracold gas of bosonic KCs molecules. We first demonstrate a cooling strategy relying on sympathetic cooling of Cs to produce…

Making molecules by mergoassociation: two atoms in adjacent nonspherical optical traps
Robert C. Bird, C. Ruth Le Sueur, Jeremy M. Hutson
Mergoassociation of two ultracold atoms to form a weakly bound molecule can occur when two optical traps that each contain a single atom are merged. Molecule formation occurs at an…
