Collisional resonances of molecules can offer a deeper understanding of interaction potentials and collision complexes, and allow control of chemical reactions. Here, we experimentally map out the spectrum of Feshbach resonances in collisions between

Abstract Almost ninety years have passed since the experiments of Farkas and Sachsse [Z. Phys. Chem. B 1933; 23:1] on para‐ortho hydrogen conversion catalyzed by paramagnetic species such as O2, but a detailed and quantitative understanding of the

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. At ultracold energies reactions are ene

Understanding collisions between ultracold molecules is crucial for making stable molecular quantum gases and harnessing their rich internal degrees of freedom for quantum engineering. Transient complexes can strongly influence collisional physics, b

Ultracold polar molecules offer strong electric dipole moments and rich internal structure, which makes them ideal building blocks to explore exotic quantum matter, implement novel quantum information schemes, or test fundamental symmetries of nature

For molecular collisions, the deflection of a molecule's trajectory provides one of the most sensitive probes of the interaction potential and there are general rules of thumb that relate the direction of deflection to precollision conditions. Follow

In this study, we achieved magnetic control of reactive scattering in an ultracold mixture of 23 Na atoms and 23 Na 6 Li molecules. In most molecular collisions, particles react or are lost near short range with unity probability, leading to the so-c

Collisions between cold polar molecules represent a fascinating research frontier but have proven hard to probe experimentally. We report measurements of inelastic cross sections for collisions between nitric oxide (NO) and deuterated ammonia (ND 3 )

Scattering resonances due to the dipole-dipole interaction between ultracold molecules, induced by static or microwave fields, are studied theoretically. We develop a method for coupled-channel calculations that can efficiently impose many short-rang

Scattering resonances are an essential tool for controlling the interactions of ultracold atoms and molecules. However, conventional Feshbach scattering resonances1, which have been extensively studied in various platforms1–7, are not expected to e
