Trap-assisted formation of atom–ion bound states

M Pinkas, O Katz, J Wengrowicz, N Akerman, R Ozeri - Nature Physics, 2023 - nature.com
Pairs of free particles cannot form bound states in an elastic collision due to momentum and
energy conservation. In many ultracold experiments, however, the particles collide in the …

False signals of chaos from quantum probes

W Kirkby, DHJ O'Dell, J Mumford - Physical Review A, 2021 - APS
We demonstrate that two-time correlation functions, which are generalizations of out-of-time-
ordered correlators (OTOCs), can show “false flags” of chaos by exhibiting behavior …

Buffer gas cooling of ions in radio-frequency traps using ultracold atoms

E Trimby, H Hirzler, H Fürst, A Safavi-Naini… - New Journal of …, 2022 - iopscience.iop.org
Reaching ultracold temperatures within hybrid atom–ion systems is a major limiting factor for
control and exploration of the atom–ion interaction in the quantum regime. In this work, we …

High-energy-resolution measurements of an ultracold-atom–ion collisional cross section
