Theoretical description of two ultracold atoms in finite 3D optical lattices using realistic interatomic interaction potentials
Sergey Grishkevich, Simon Sala, Alejandro Saenz
A theoretical approach is described for an exact numerical treatment of a pair of ultracold atoms interacting via a central potential that are trapped in a finite three-dimensional…

Mimicking multi-channel scattering with single-channel approaches
Sergey Grishkevich, Philipp-Immanuel Schneider, Yulian V. Vanne +1
The collision of two atoms is an intrinsic multi-channel (MC) problem as becomes especially obvious in the presence of Feshbach resonances. Due to its complexity, however, single-c…
