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 ...

Towards Ultracold Organic Chemistry: Prospects of Laser Cooling Large Organic Molecules [PDF]
The Journal of Physical Chemistry Letters, 2020 Ultracold organic chemistry enables studies of reaction dynamics and mechanisms in quantum regime. Access to ultracold molecules hinges on the ability to efficiently scattermultiple photons via quasi-closed cycling transitions and, in practice, is complicated by the complex electronic structure of polyatomic molecules.

Direct Frequency Comb Laser Cooling and Trapping
Physical Review X, 2016 Ultracold atoms, produced by laser cooling and trapping, have led to recent advances in quantum information, quantum chemistry, and quantum sensors. A lack of ultraviolet narrow-band lasers precludes laser cooling of prevalent atoms such as hydrogen ...

Cold interactions and chemical reactions of linear polyatomic anions with alkali-metal and alkaline-earth-metal atoms [PDF]
, 2017 We consider collisional studies of linear polyatomic ions immersed in ultracold atomic gases and investigate the intermolecular interactions and chemical reactions of several molecular anions ($\mathrm{OH}^-$, $\mathrm{CN}^-$, $\mathrm{NCO}^-$, $\mathrm ...

Magnetic tuning of ultracold barrierless chemical reactions
Physical Review Research, 2020 While attaining external field control of bimolecular chemical reactions has long been a coveted goal of physics and chemistry, the role of hyperfine interactions and dc magnetic fields in achieving such control has remained elusive.

Buffer gas loaded magneto-optical traps for Yb, Tm, Er and Ho
New Journal of Physics, 2014 Direct loading of lanthanide atoms into magneto-optical traps (MOTs) from a very slow cryogenic buffer gas beam source is achieved, without the need for laser slowing. The beam source has an average forward velocity of 60– $70\;{\rm m}\;{{{\rm s}}^{-1}}$

Observation of pendular butterfly Rydberg molecules
Nature Communications, 2016 Rydberg molecules have potential for ultracold chemistry applications in light of their unconventional binding mechanism that provides high tunability. Here the authors observe and control butterfly Rydberg molecules, which are bound by a shape resonance
