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…

Long-range states in collisions of ultracold molecules
James F. E. Croft, Brian K. Kendrick, Jeremy M. Hutson
We use coupled-channel calculations to explore the nature of near-threshold bound states in a simplified model of Rb+KRb. This is a prototype for systems with very strong coupling…
