Roadmap on Quantum Sensors for Vacuum Metrology
D. S. Barker, J. L. Booth, S. P. Eckel +7
We describe how laser-cooled and trapped alkali-metal atoms have been used as pressure sensors in the high- and ultra-high-vacuum regimes operating with relative uncertainties of j…
Boundaries of universality of thermal collisions for atom-atom scattering
Xuyang Guo, Kirk W. Madison, James L. Booth +1
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 rat…
Revising the Universality Hypothesis for Room-temperature Collisions
James L. Booth, Kirk W. Madison
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 sens…
Cross-calibration of atomic sensors for pressure metrology
Erik Frieling, Riley A. Stewart, James L. Booth +1
Atomic sensors have shown great promise for density and pressure metrology in the high, ultra-high, and extremely-high vacuum regimes. Specifically, the density of background gas p…
Trapped particle evolution driven by residual gas collisions
Avinash Deshmukh, Riley A. Stewart, Pinrui Shen +2
We present a comprehensive mathematical model and experimental measurements for the evolution of a trapped particle ensemble driven by collisions with a room-temperature background…
Cross-calibration of atomic pressure sensors and deviation from quantum diffractive collision universality for light particles
Pinrui Shen, Erik Frieling, Katherine R. Herperger +6
The total room-temperature, velocity-averaged cross section for atom-atom and atom-molecule collisions is well approximated by a universal function depending only on the magnitude…
