Optical production of ultracold polar molecules [PDF]
AIP Conference Proceedings, 2005 We demonstrate the production of ultracold polar RbCs molecules in their vibronic ground state, via photoassociation of laser-cooled atoms followed by a laser-stimulated state transfer process. The resulting sample of $X ^1 ^+ (v=0)$ molecules has a translational temperature of $\sim100 $K and a narrow distribution of rotational states.

Ultracold molecules: a platform for quantum simulation [PDF]
Quantum Science and Technology, 2018 We explore the uses of ultracold molecules as a platform for future experiments in the field of quantum simulation, focusing on two molecular species, $^{40}$Ca$^{19}$F and $^{87}$Rb$^{133}$Cs.

Photoinduced Two-Body Loss of Ultracold Molecules. [PDF]
Physical Review Letters, 2019 The lifetime of nonreactive ultracold bialkali gases was conjectured to be limited by sticky collisions amplifying three-body loss. We show that the sticking times were previously overestimated and do not support this hypothesis.

Ultracold Gas of Dipolar NaCs Ground State Molecules. [PDF]
Physical Review Letters, 2022 We report on the creation of bosonic NaCs molecules in their absolute rovibrational ground state via stimulated Raman adiabatic passage. We create ultracold gases with up to 22 000 dipolar NaCs molecules at a temperature of 300(50) nK and a peak density ...

Ultracold chemistry and its reaction kinetics
New Journal of Physics, 2015 We study the reaction kinetics of chemical processes occurring in the ultracold regime and systematically investigate their dynamics. Quantum entanglement is found to play a key role in driving an ultracold reaction towards a dynamical equilibrium.

Microwave Shielding of Ultracold Polar Molecules [PDF]
Physical Review Letters, 2018 We use microwaves to engineer repulsive long-range interactions between ultracold polar molecules. The resulting shielding suppresses various loss mechanisms and provides large elastic cross sections. Hyperfine interactions limit the shielding under realistic conditions, but a magnetic field allows suppression of the losses to below 10-14 cm3 s-1.

Efficient pathway to NaCs ground state molecules
New Journal of Physics, 2023 We present a study of two-photon pathways for the transfer of NaCs molecules to their rovibrational ground state. Starting from NaCs Feshbach molecules, we perform bound-bound excited state spectroscopy in the wavelength range from 900 nm to 940 nm ...

Electron Electric Dipole Moment Searches Using Clock Transitions in Ultracold Molecules.
Physical Review Letters, 2020 Permanent electric dipole moments (EDMs) of fundamental particles such as the electron are signatures of parity and time-reversal violation occurring in physics beyond the standard model.
