Cold atomic gases have become a paradigmatic system for exploring fundamental physics,
which at the same time allows for applications in quantum technologies. The accelerating …

We measure inelastic collisions between ultracold CaF molecules by combining two optical
tweezers, each containing a single molecule. We observe collisions between Σ 2 CaF …

We theoretically investigate the properties of highly polar diatomic molecules containing S 2-
state transition-metal atoms. We calculate potential energy curves, permanent electric dipole …

We study the ground-state entanglement between two atoms in a two-dimensional isotropic
harmonic trap. We consider a finite-range soft-core interaction that can be applied to …

Ultracold molecules trapped in optical tweezers show great promise for the implementation
of quantum technologies and precision measurements. We study a prototypical scenario …

Results for elastic atom-atom scattering are obtained as a first practical application of
RmatReact, a new code for generating high-accuracy scattering observables from potential …

The two trapped quantum particles interacting problem is generalized to three dimensions,
and the exact Coulomb potential is used. The system is solved by expanding the …

We reveal the existence of polarizing quantum phases for the enantiomers of cold,
interacting chiral molecules in an optical helicity lattice by means of an extended Bose …

The rotational and fine structure of open-shell molecules in a Σ electronic state gives rise to
crossings between Zeeman states of different parity. These crossings become avoided in the …

Exactly solvable model of two Rydberg-dressed atoms moving in a quasi-two-dimensional
harmonic trap is introduced and its properties are investigated. Depending on the strength of …
