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 …

We theoretically investigate the properties of two interacting ultracold highly magnetic atoms
trapped in a one-dimensional harmonic potential. The atoms interact via an anisotropic long …

Optical tweezer arrays are useful tools for manipulating single atoms and molecules. An
exciting avenue for research with optical tweezers is using the interactions between polar …

We examine the potential-energy curves and polarization of the dipole moments of two static
polar molecules under the influence of an external dc electric field and their anisotropic …

(English) Quantum many-body physics poses a substantial computational challenge
