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…
Shielding collisions of ultracold CaF molecules with static electric fields
Bijit Mukherjee, Matthew D. Frye, C. Ruth Le Sueur +2
We study collisions of ultracold CaF molecules in strong static electric fields. These fields allow the creation of long-range barriers in the interaction potential, effectively pr…
Formation of ultracold molecules by merging optical tweezers
Daniel K. Ruttley, Alexander Guttridge, Stefan Spence +4
We demonstrate the formation of a single RbCs molecule during the merging of two optical tweezers, one containing a single Rb atom and the other a single Cs atom. Both atoms are in…
User Manual for MOLSCAT, BOUND and FIELD, Version 2025.0: programs for quantum scattering properties and bound states of interacting pairs of atoms and molecules
Jeremy M. Hutson, C. Ruth Le Sueur
MOLSCAT is a general-purpose package for performing non-reactive quantum scattering calculations for atomic and molecular collisions using coupled-channel methods. Simple atom-mole…
Observation of interspecies Feshbach resonances in an ultracold K-Cs mixture and refinement of interaction potentials
Michael Gröbner, Philipp Weinmann, Emil Kirilov +4
We observe interspecies Feshbach resonances due to s-wave bound states in ultracold K-Cs scattering for three different spin mixtures. The resonances are observed as…
Measurement of the binding energy of ultracold RbCs molecules using an offset-free optical frequency comb
Peter K. Molony, Avinash Kumar, Philip D. Gregory +6
We report the binding energy of RbCs molecules in their rovibrational ground state measured using an offset-free optical frequency comb based on difference frequency…
Creation of ultracold RbCs molecules in the rovibrational ground state
Peter K. Molony, Philip D. Gregory, Zhonghua Ji +6
We report the creation of a sample of over 1000 ultracold RbCs molecules in the lowest rovibrational ground state, from an atomic mixture of Rb and Cs, by magnetoasso…
Ultracold dense samples of dipolar RbCs molecules in the rovibrational and hyperfine ground state
Tetsu Takekoshi, Lukas Reichsöllner, Andreas Schindewolf +6
We produce ultracold dense trapped samples of 87Rb133Cs molecules in their rovibrational ground state, with full nuclear hyperfine state control, by stimulated Raman adiabatic pass…
Production of optically trapped RbCs Feshbach molecules
Michael P. Köppinger, Daniel J. McCarron, Daniel L. Jenkin +6
We report the production of RbCs Feshbach molecules in a crossed-beam dipole trap. A mixture of Rb and Cs is cooled close to quantum degeneracy before an inte…
Generating mesoscopic Bell states via collisions of distinguishable quantum bright solitons
Bettina Gertjerenken, Thomas P. Billam, Caroline L. Blackley +4
We investigate numerically the collisions of two distinguishable quantum matter-wave bright solitons in a one-dimensional harmonic trap. We show that such collisions can be used to…
Towards the production of ultracold ground-state RbCs molecules: Feshbach resonances, weakly bound states, and coupled-channel model
Tetsu Takekoshi, Markus Debatin, Raffael Rameshan +8
We have studied interspecies scattering in an ultracold mixture of Rb and Cs atoms, both in their lowest-energy spin states. The three-body loss signatures of 30 inc…
