Toward improved loading, cooling, and trapping of molecules in magneto-optical traps
New Journal of Physics, 2023 Recent experiments have demonstrated direct cooling and trapping of diatomic and triatomic molecules in magneto-optical traps (MOTs). However, even the best molecular MOTs to date still have density 10 ^−5 times smaller than in typical atomic MOTs.

Maximizing the capture velocity of molecular magneto-optical traps with Bayesian optimization
New Journal of Physics, 2021 Magneto-optical trapping (MOT) is a key technique on the route towards ultracold molecular ensembles. However, the realization and optimization of magneto-optical traps with their wide parameter space is particularly difficult.

High-resolution mid-infrared spectroscopy of buffer-gas-cooled methyltrioxorhenium molecules
New Journal of Physics, 2017 We demonstrate cryogenic buffer-gas cooling of gas-phase methyltrioxorhenium (MTO). This molecule is closely related to chiral organometallic molecules where the parity-violating energy differences between enantiomers is measurable.
