We prepare pairs of ^133 Cs atoms in a single optical tweezer and perform Feshbach spectroscopy for collisions of atoms in the states ( f = 3, m _f = ±3). We detect enhancements in pair loss using a detection scheme where the optical tweezers are re

We explore the properties of three-atom complexes of alkali-metal diatomic molecules with alkali-metal atoms, which may be formed in ultracold collisions. We estimate the densities of vibrational states at the energy of atom–diatom collisions, and

We present measurements of more than 80 magnetic Feshbach resonances in collisions of ultracold ^23 Na ^40 K with ^40 K. We assign quantum numbers to a group of low-field resonances and show that they are probably due to long-range states of the tria

We report the preparation of exactly one ^87 Rb atom and one ^133 Cs atom in the same optical tweezer as the essential first step towards the construction of a tweezer array of individually trapped ^87 Rb ^133 Cs molecules. Through careful selection

We study inelastic collisions between CaF molecules and ^87 Rb atoms in a dual-species magneto-optical trap. The presence of atoms increases the loss rate of molecules from the trap. By measuring the loss rates and density distributions, we determine

Understanding ultracold collisions involving molecules is of fundamental importance for current experiments, where inelastic collisions typically limit the lifetime of molecular ensembles in optical traps. Here we present a broad study of optically t

We discuss how the internal structure of ultracold molecules, trapped in the motional ground state of optical tweezers, can be used to implement qudits. We explore the rotational, fine and hyperfine structure of ^40 Ca ^19 F and ^87 Rb ^133 Cs, which

Abstract Bose-Einstein condensates of ultracold atoms serve as low-entropy sources for a multitude of quantum-science applications, ranging from quantum simulation and quantum many-body physics to proof-of-principle experiments in quantum metrology a

We investigate the behaviour of single-channel theoretical models of cold and ultracold collisions that take account of inelastic and reactive processes using a single parameter to represent short-range loss. We present plots of the resulting energy-

Trapped samples of ultracold molecules are often short-lived because close collisions between them result in trap loss. We investigate the use of shielding with static electric fields to create repulsive barriers between polar molecules to prevent su
