Dipolar Collisions of Ultracold Ground-State Bosonic Molecules
Physical Review X, 2018 The dipolar collision between ultracold polar molecules is an important topic both by its own right from the fundamental point of view and for the successful exploration of many-body physics with strong and long-range dipolar interactions.

Reaction kinetics of ultracold molecule-molecule collisions [PDF]
Nature Communications, 2018 AbstractStudying chemical reactions on a state-to-state level tests and improves our fundamental understanding of chemical processes. For such investigations it is convenient to make use of ultracold atomic and molecular reactants as they can be prepared in well defined internal and external quantum states.

Quantum dynamics of tunneling dominated reactions at low temperatures
New Journal of Physics, 2015 We report a quantum dynamics study of the Li + HF → LiF + H reaction at low temperatures of interest to cooling and trapping experiments. Contributions from non-zero partial waves are analyzed and results show narrow resonances in the energy dependence ...

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.

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.

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.
