The angular momentum of molecules, or, equivalently, their rotation in three-dimensional
space, is ideally suited for quantum control. Molecular angular momentum is naturally …

We derive the generalization of Wigner's causality bounds and Bethe's integral formula for
the effective range parameter to arbitrary dimension and arbitrary angular momentum. We …

We study the near-threshold molecular and collisional physics of a strong K 40 p-wave
Feshbach resonance through a combination of measurements, numerical calculations, and …

We extend the powerful formalism of multichannel quantum defect theory combined with a
frame transformation to ultracold atom-molecule collisions in magnetic fields. By solving the …

Understanding quantum many-body systems with strong interactions and unconventional
phases therein is one of the most challenging tasks in physics. In cold atom physics, this has …

Progress in ultracold experiments with polar molecules requires a clear understanding of
their interactions and reactivity at ultralow collisional energies. Two important theoretical …

We describe the cold-atom vacuum standards (CAVS) under development at the National
Institute of Standards and Technology (NIST). The CAVS measures pressure in the ultra …

From a rigorous multichannel quantum-defect formulation of bimolecular processes, we
derive a fully quantal and analytic model for the total rate of exoergic bimolecular reactions …

Trapped ultracold alkali-metal atoms can be used to measure pressure in the ultra-high-
vacuum and XHV pressure regimes, those with p< 10− 6 Pa. This application for ultracold …

High partial-wave (l≥ 2) Feshbach resonance (FR) in an ultracold mixture of Rb 85-Rb 87
atoms is investigated experimentally aided by a partial-wave insensitive analytic …
