Effect of glancing collisions in the cold-atom vacuum standard
We theoretically investigate the effect of “glancing” collisions on the ultra-high-vacuum
pressure readings of the cold-atom vacuum standard (CAVS), based on either ultracold Li 7 …

Boundaries of universality of thermal collisions for atom-atom scattering
Thermal rate coefficients for some atomic collisions have been observed to be remarkably
independent of the details of interatomic interactions at short range. This makes these rate …

Revising the universality hypothesis for room-temperature collisions
Atoms constitute promising quantum sensors for a variety of scenarios including vacuum
metrology. Key to this application is knowledge of the collision rate coefficient of the sensor …

Cross-calibration of quantum atomic sensors for pressure metrology
Quantum atomic sensors have shown great promise for vacuum metrology. Specifically, the
density of gas particles in vacuum can be determined by measuring the collision rate …
