Non-perturbative theoretical description of two atoms in an optical lattice with time-dependent perturbations
Philipp-Immanuel Schneider, Sergey Grishkevich, Alejandro Saenz
A theoretical approach for a non-perturbative dynamical description of two interacting atoms in an optical lattice potential is introduced. The approach builds upon the stationary…
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…
Exact theoretical description of two ultracold atoms in a single site of a 3D optical lattice using realistic interatomic interaction potentials
Sergey Grishkevich, Alejandro Saenz
A theoretical approach was developed for an exact numerical description of a pair of ultracold atoms interacting via a central potential that are trapped in a three-dimensional opt…
Ab-initio determination of Bose-Hubbard parameters for two ultracold atoms in an optical lattice using a three-well potential
Philipp-Immanuel Schneider, Sergey Grishkevich, Alejandro Saenz
We calculate numerically the exact energy spectrum of the six dimensional problem of two interacting Bosons in a three-well optical lattice. The particles interact via a full Born-…
Influence of a tight isotropic harmonic trap on photoassociation in ultracold homonuclear alkali gases
Sergey Grishkevich, Alejandro Saenz
The influence of a tight isotropic harmonic trap on photoassociation of two ultracold alkali atoms forming a homonuclear diatomic is investigated using realistic atomic interaction…
