Signatures of Non-universal Quantum Dynamics of Ultracold Chemical Reactions of Polar Alkali Dimer Molecules with Alkali Metal Atoms: Li(2S) + NaLi(a3Σ+) → Na(2S) + Li2(a3Σu+). [PDF]
Journal of Physical Chemistry Letters, 2023 Ultracold chemical reactions of weakly bound triplet-state alkali metal dimer molecules have recently attracted much experimental interest. We perform rigorous quantum scattering calculations with a new ab initio potential energy surface to explore the ...

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.

Quantum computation and quantum simulation with ultracold molecules [PDF]
Nature PhysicsUltracold molecules confined in optical lattices or tweezer traps can be used to process quantum information and simulate the behaviour of many-body quantum systems. Molecules offer several advantages for these applications.

Ultracold molecules and ultracold chemistry
Molecular Physics, 2009 The recent development of a range of new methods for producing samples of gas phase molecules that are translationally cold (T < 1 K) or ultracold (T < 1 mK) is driving efforts to study reactive and inelastic collisional processes in these temperature regimes. In this review article the new methods for cold/ultracold molecule production are reviewed in

Resonant Dipolar Collisions of Ultracold Molecules Induced by Microwave Dressing. [PDF]
Physical Review Letters, 2020 We demonstrate microwave dressing on ultracold, fermionic ^{23}Na^{40}K ground-state molecules and observe resonant dipolar collisions with cross sections exceeding 3 times the s-wave unitarity limit.

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 ...
