Magnetic Feshbach resonances in ultracold collisions between Cs and Yb atoms.

Yang, B. C. and Frye, Matthew D. and Guttridge, A. and Aldegunde, Jesus and Żuchowski, Piotr S. and Cornish, Simon L. and Hutson, Jeremy M. (2019) 'Magnetic Feshbach resonances in ultracold collisions between Cs and Yb atoms.', Physical review A., 100 (2). 022704.


We investigate magnetically tunable Feshbach resonances in ultracold collisions between ground-state Yb and Cs atoms, using coupled-channel calculations based on an interaction potential recently determined from photoassociation spectroscopy. We predict resonance positions and widths for all stable isotopes of Yb, together with resonance decay parameters where appropriate. The resonance patterns are richer and more complicated for fermionic Yb than for spin-zero isotopes, because there are additional level splittings and couplings due to scalar and tensorial Yb hyperfine interactions. We examine collisions involving Cs atoms in a variety of hyperfine states and identify resonances that appear most promising for experimental observation and for magnetoassociation to form ultracold CsYb molecules.
