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 …

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 …

Controlling the interactions in a cold atom quantum impurity system

T Hewitt, T Bertheas, M Jain, Y Nishida… - Quantum Science and …, 2024 - iopscience.iop.org
We implement an experimental architecture in which a single atom of K is trapped in an
optical tweezer, and is immersed in a bath of Rb atoms at ultralow temperatures. In this …

Spin dynamics dominated by resonant tunneling into molecular states

YK Lee, H Lin, W Ketterle - Physical Review Letters, 2023 - APS
Optical lattices and Feshbach resonances are two of the most ubiquitously used tools in
atomic physics, allowing for the precise control, discrete confinement, and broad tunability of …

Confinement-induced field-linked states of ultracold polar molecules

RRW Wang, JL Bohn - arXiv preprint arXiv:2409.08431, 2024 - arxiv.org
We predict the existence of stable bound states between pairs of ultracold diatomic
molecules with the aid of a static electric field and 1D harmonic confinement. We focus on …
