Ultracold molecules offer unprecedented opportunities for the controlled interrogation of
molecular events, including chemical reactivity in the ultimate quantum regime. The …

In the past two decades, the revolutionary technologies of creating cold and ultracold
molecules have provided cutting-edge experiments for studying the fundamental …

Dynamics of bimolecular reactions in the gas phase are of foundational importance in
combustion, atmospheric chemistry, interstellar chemistry, and plasma chemistry. These …

The role of internal molecular degrees of freedom, such as rotation, has scarcely been
explored experimentally in low-energy collisions despite their significance to cold and …

Electronically non-adiabatic effects play an important role in many chemical reactions.
However, how these effects manifest in cold and ultracold chemistry remains largely …

We report on the observation of magnetic Feshbach resonances in a Fermi-Fermi mixture of
ultracold atoms with extreme mass imbalance and on their unique p-wave dominated three …

The geometric phase is shown to control the outcome of an ultracold chemical reaction. The
control is a direct consequence of the sign change on the interference term between two …

A fundamental question in the study of chemical reactions is how reactions proceed at a
collision energy close to absolute zero. This question is no longer hypothetical: quantum …

Quantum reactive scattering calculations for the hydrogen exchange reaction H+ H 2 (v= 4,
j= 0)→ H+ H 2 (v′, j′) and its isotopic analogues are reported for ultracold collision …

A new electronically non-adiabatic quantum reactive scattering methodology is presented
based on a time-independent coupled channel formalism and the adiabatically adjusting …
