Product-state distribution after isotopic substitution in ultracold atom-molecule collisions
Maciej B. Kosicki, Piotr S. Żuchowski, Maykel L. González-Martínez +1
We show that products of the isotopic substitution reactions in experimentally accessible molecules such as NaK, RbCs, and SrF are cold according to their translational energy belo…
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…
Benchmarking the accuracy of seniority-zero wavefunction methods for non-covalent interactions
Filip Brzęk, Katharina Boguslawski, Paweł Tecmer +1
In this paper, we scrutinize the ability of seniority-zero wavefunction-based methods to model different types of non-covalent interactions, such as hydrogen bonds, dispersion, and…
Nonrigidity effects -- a missing puzzle piece in the description of low-energy anisotropic molecular collisions
Mariusz Pawlak, Piotr S. Żuchowski, Nimrod Moiseyev +1
Cold collisions serve as a very sensitive probe of the interaction potential. In the recent study of Klein et al. (Nature Phys. 13, 35-38 (2017)) the one-parameter scaling of the i…
Magnetic Feshbach resonances in ultracold collisions between Cs and Yb atoms
B. C. Yang, Matthew D. Frye, A. Guttridge +4
We investigate magnetically tunable Feshbach resonances in ultracold collisions between ground-state Yb and Cs atoms, using coupled-channel calculations based on an interaction pot…
Modeling the electronic structures of the ground and excited states of the ytterbium atom and the ytterbium dimer: A modern quantum chemistry perspective
Paweł Tecmer, Katharina Boguslawski, Mateusz Borkowski +2
We present a comprehensive theoretical study of the electronic structures of the Yb atom and the Yb molecule, respectively, focusing on their ground and lowest-lying electronic…
