Isotopic effect on collisional widths and shifts of Hg clock transition induced by cold Rb atoms
Renu Bala, Adam Linek, Marcin Witkowski +4
We study the isotopic dependence of collisional widths and shifts of the Hg clock transition S-P perturbed by the Rb atoms in the temperature range from 1 nK to 1 K…
Production of ultracold asymmetric tops from Sr atoms and SrOH molecules
Maciej B. Kosicki, Mateusz Borkowski, Marcin Umiński +1
We report the comprehensive theoretical investigation of the Sr-SrOH system identifying it as a promising route to production of ultracold asymmetric top molecules. Combining high-…
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 b…
Spin--spin interaction and magnetic Feshbach resonances in collisions of high-spin atoms with closed-shell atoms
Matthew D. Frye, Piotr S. Żuchowski, Michał Tomza
We investigate interactions and ultracold collisions of high-spin but spherical atoms with closed-shell atoms, focussing on the example of Cr with Yb. Such a combination has only o…
Observation of the P-wave Shape Resonance
Baruch Margulis, Prerna Paliwal, Wojciech Skomorowski +3
Partial wave resonances are quasi-bound states that are formed by tunneling through the centrifugal barrier. Such states are important to collisions that deviate from the Langevin…
Quantum chaos in Feshbach resonances of the ErYb system
Maciej B. Kosicki, Mateusz Borkowski, Piotr S. Żuchowski
We investigate ultracold magnetic-field-assisted collisions in the so far unexplored ErYb system. The nonsphericity of the Er atom leads to weakly anisotropic interactions that pro…
