This review is concerned with the physics and chemistry associated with the interactions,
collisions, and reactions of ultracold molecules, that is, molecules having translational …

Our main knowledge about astrophysical environments relies on radiative spectra.
Absorption studies require background sources that are located hapharzadly in …

Ultracold molecules offer unprecedented opportunities for the controlled interrogation of
molecular events, including chemical reactivity in the ultimate quantum regime. The …

We propose a novel direct detection concept to search for dark matter with 100 keV to 100
MeV masses. Such dark matter can scatter off molecules in a gas and transfer an O (1) …

We report a new full-dimensional potential energy surface (PES) for the inelastic scattering
between ro-vibrationally excited H2 molecules. The new PES is based on 39,462 multi …

Molecular collisions are of fundamental importance in understanding intermolecular
interaction and dynamics. Its importance is accentuated in cold and ultra-cold collisions …

Measuring inelastic rates with partial-wave resolution requires temperatures close to a
Kelvin or below, even for the lightest molecule. In a recent experiment, Perreault, Mukherjee …

As the most abundant molecule in the universe, collisions involving H2 have important
implications in astrochemistry. Collisions between hydrogen molecules also represent a …

Accurate rate coefficients for molecular vibrational transitions due to collisions with H2,
critical for interpreting infrared astronomical observations, are lacking for most molecules …

The H2+ H2 system has long been considered a benchmark system for ro-vibrational energy
transfer in bimolecular collisions. However, most studies thus far have focused on collisions …
