Hybrid systems of laser-cooled trapped ions and ultracold atoms combined in a single
experimental setup have recently emerged as a new platform for fundamental research in …

The role of internal molecular degrees of freedom, such as rotation, has scarcely been
explored experimentally in low-energy collisions despite their significance to cold and …

A scattering model is developed for ultracold molecular collisions, which allows inelastic
processes, chemical reactions, and complex formation to be treated in a unified way. All …

We consider the coherent control of ultracold molecule–molecule scattering, impacted by a
dense set of rovibrational resonances. To characterize the resonance spectrum, a …

Quantum reactive and elastic cross sections and rate coefficients have been calculated for
D++ H 2 (v= 0, j= 0) collisions in the energy range from 10− 8 K (deep ultracold regime) …

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 …

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 …

Resonant exchange is a general process playing a key role in many-body dynamics and
transport phenomena, such as spin, charge, or excitation diffusion. The underlying process …

While the thermodynamics for bosonic systems with weak s-wave interactions has been
known for decades, a general and systematic extension to higher partial waves has not yet …

While collision lifetimes are a fundamental property of few-body scattering events, their
behavior at ultralow temperatures is not completely understood. Using multichannel …
