Active stabilization of kilogauss magnetic fields to the ppm level for magnetoassociation on ultranarrow Feshbach resonances
Mateusz Borkowski, Lukas Reichsöllner, Premjith Thekkeppatt +4
Feshbach association of ultracold molecules using narrow resonances requires exquisite control of the applied magnetic field. Here we present a magnetic field control system to del…
The RbSr ground state investigated via spectroscopy of hot & ultracold molecules
Alessio Ciamei, Jacek Szczepkowski, Alex Bayerle +9
We report on spectroscopic studies of hot and ultracold RbSr molecules, and combine the results in an analysis that allows us to fit a potential energy curve (PEC) for the X(1)$^2Σ…
Observation of Feshbach resonances between alkali and closed-shell atoms
Vincent Barbé, Alessio Ciamei, Benjamin Pasquiou +4
Magnetic Feshbach resonances are an invaluable tool for controlling ultracold atoms and molecules. They can be used to tune atomic interactions and have been used extensively to ex…
