Simple model of Feshbach resonance in the strong-coupling regime
T. Wasak, M. Krych, Z. Idziaszek +3
We use the dressed potentials obtained in the adiabatic representation of two coupled channels to calculate s-wave Feshbach resonances in a 3D spherically symmetric potential with…
Quantum defect model of a reactive collision at finite temperature
Krzysztof Jachymski, Michał Krych, Paul S. Julienne +1
We consider a general problem of inelastic collision of particles interacting with power-law potentials. Using quantum defect theory we derive an analytical formula for the energy-…
Quantum theory of reactive collisions for 1/r^n potentials
Krzysztof Jachymski, Michal Krych, Paul S. Julienne +1
We develop a general quantum theory for reactive collisions involving power-law potentials (-1/r^n) valid from the ultracold up to the high-temperature limit. Our quantum defect fr…
Sympathetic cooling of the Ba ion by collisions with ultracold Rb atoms: theoretical prospects
Michał Krych, Wojciech Skomorowski, Filip Pawłowski +2
State-of-the-art {\em ab initio} techniques have been applied to compute the potential energy curves of the (BaRb) molecular ion in the Born-Oppenheimer approximation. The long…
