Cold atom–ion experiments in hybrid traps
A Härter, J Hecker Denschlag - Contemporary Physics, 2014 - Taylor & Francis
In the last five years, a novel field of physics and chemistry has developed in which cold
trapped ions and ultracold atomic gases are brought into contact with each other. Combining …

Formation of ultracold molecules by merging optical tweezers
DK Ruttley, A Guttridge, S Spence, RC Bird… - Physical Review Letters, 2023 - APS
We demonstrate the formation of a single RbCs molecule during the merging of two optical
tweezers, one containing a single Rb atom and the other a single Cs atom. Both atoms are …

Power-law distributions for a trapped ion interacting with a classical buffer gas
RG DeVoe - Physical review letters, 2009 - APS
Classical collisions with an ideal gas generate non-Maxwellian distribution functions for a
single ion in a radio frequency ion trap. The distributions have power-law tails whose …
