Linking Ultracold Polar Molecules [PDF]
Physical 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.

Production of Ultracold XOH (X = Ca, Sr, Ba) Molecules by Direct Laser Cooling: A Theoretical Study Based on Accurate Ab Initio Calculations. [PDF]
MoleculesEffective laser cooling schemes are fundamental for preparing ultracold triatomic molecules. Here, efficient laser cooling strategies for alkaline-earth hydroxides (XOH, X = Ca, Sr, Ba) are proposed using high-precision quantum calculations. By mapping Λ-

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

Complexes formed in collisions between ultracold alkali-metal diatomic molecules and atoms
New Journal of Physics, 2021 We explore the properties of three-atom complexes of alkali-metal diatomic molecules with alkali-metal atoms, which may be formed in ultracold collisions.

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.

Ab initio study of the reactivity of ultracold RbSr + RbSr collisions
New Journal of Physics, 2022 We performed ab initio calculations in order to assess the reactivity of ultracold RbSr $({}^{2}{\Sigma}^{+})$ + RbSr $({}^{2}{\Sigma}^{+})$ collisions occurring on the singlet as well as the triplet potential.

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.
