Microwave shielding enables efficient evaporative cooling of NaK molecules.
Nature 607, 677 (2022)
Hard-collision glory scattering
Unexpected forward scattering in molecular collisions with large amounts of energy transfer.
Nature Chemistry 14, 664 (2022)
Controlling reactions by interference
Chemical reactions between NaLi molecules and Na atoms are controlled using Feshbach resonances.
Science 375, 1006 (2022)
Shielding realized experimentally!
First experimental realization of microwave shielding, using CaF molecules in optical tweezers.
Science 373, 779 (2021)
Interactions between molecules can be controlled using microwaves.
We show how this gives access to strong resonant dipolar interactions.
Phys. Rev. Lett. 125, 063401 (2020)
Experiments on ultracold KRb molecules quantitatively confirm our theory of collision complex lifetimes and photo-excitation rates.
Nature Physics 16, 1132 (2020)
Collisions between ultracold molecules lead to loss mediated by formation of complexes.
Our new theory quantifies the lifetime of these complexes and indicates their loss could be to due photo-excitation.
Phys. Rev. Lett. 123, 123402 (2019)
Microwaves can be used to engineer repulsive interactions between molecules that can prevent losses while maintaining large elastic cross sections, key to cooling molecules to high phase-space density.
