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…
Measurement of Rb-Rb van der Waals coefficient via Quantum Diffractive Universality
Riley A. Stewart, Pinrui Shen, James L. Booth +1
Collisions between trapped atoms or trapped molecules with room temperature particles in the surrounding vacuum induce loss of the trapped population at a rate proportional to the…
Optical Quenching of Metastable Helium Atoms using Excitation to the State
Jiwen Guan, Vivien Behrendt, Pinrui Shen +5
Discharge and electron-impact excitation lead to the production of metastable helium atoms in two metastable states, 2S and 2S. However, many applications require p…
Universality of Diffractive Collisions and the Quantum Pressure Standard
James L. Booth, Pinrui Shen, Roman V. Krems +1
This work demonstrates that quantum diffractive collisions, those that result in very small momentum and energy transfer, are universal. Specifically, the cumulative energy distrib…
