Magnetic Feshbach resonances in Ba+Li collisions due to strong spin-orbit coupling
Masato Morita, Joachim Siemund, Wei Wu +8
We report a pronounced dependence of magnetic Feshbach resonance spectra on the initial hyperfine-Zeeman state of Li in ultracold Ba+Li collisions. The measured num…

Magnetic Feshbach resonances in ultracold atom-molecule collisions
Masato Morita, Maciej B. Kosicki, Piotr S. Zuchowski +2
We report numerically exact quantum scattering calculations on magnetic Feshbach resonances in ultracold, strongly anisotropic atom-molecule [Rb(S) + SrF()] collisions…

Multichannel quantum defect theory with a frame transformation for ultracold atom-molecule collisions in magnetic fields
Masato Morita, Paul Brumer, Timur V. Tscherbul
We extend the powerful formalism of multichannel quantum defect theory combined with a frame transformation to ultracold atom-molecule collisions in magnetic fields. By solving the…
