Linking Ultracold Polar Molecules [PDF]

open access: yesPhysical Review Letters, 2003
We predict that pairs of polar molecules can be weakly bound together in an ultracold environment, provided that a dc electric field is present. The field that links the molecules together also strongly influences the basic properties of the resulting dimer, such as its binding energy and predissociation lifetime.

Optical production of ultracold polar molecules [PDF]

open access: yesAIP 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 $X ^1Σ^+ (v=0)$ molecules has a translational temperature of $\sim100 μ$K and a narrow distribution of rotational states.

Microwave Shielding of Ultracold Polar Molecules [PDF]

open access: yesPhysical 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.

Reaction kinetics of ultracold molecule-molecule collisions [PDF]

open access: yesNature 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.
