Feshbach spectroscopy of Cs atom pairs in optical tweezers
RV Brooks, A Guttridge, MD Frye… - New Journal of …, 2022 - iopscience.iop.org
We prepare pairs of 133 Cs atoms in a single optical tweezer and perform Feshbach
spectroscopy for collisions of atoms in the states (f= 3, mf=±3). We detect enhancements in …

Simple, paradigmatic systems are important tools in understanding strongly correlated
systems. One such system is the Bose-Hubbard model, which can be realized using atoms …

Abstract Taking the ultracold 85 Rb–87 Rb collision system as an example, we investigated
the Feshbach resonances of nonzero partial waves above the threshold. The self-energy at …

Control and Collisions of 87Rb and 133Cs Atoms in Optical Tweezers
R BROOKS - 2022 - etheses.dur.ac.uk
This thesis reports the first steps towards the production of an optical tweezer array of
ultracold 87Rb133Cs molecules. Such a system represents a longstanding goal: the full …
