One- and two-atom states in a rotating ring lattice
Juha Javanainen, Otim Odong, Jerome C. Sanders
We study the states of one and two atoms in a rotating ring lattice in a Hubbard type tight-binding model. The model is developed carefully from basic principles in order to proper…
Heterodimer of two distinguishable atoms in a one-dimensional optical lattice
Otim Odong, Jerome C. Sanders, Juha Javanainen
Within the Bose-Hubbard model, we theoretically determine the stationary states of two distinguishable atoms in a one-dimensional optical lattice and compare with the case of two i…
Bound states of two bosons in an optical lattice near an association resonance
Jerome C. Sanders, Otim Odong, Juha Javanainen +1
We model two bosons in an optical lattice near a Feshbach or photoassociation resonance, focusing on the Bose-Hubbard model in one dimension. Whereas the usual atoms-only theory wi…
Dimer of two bosons in a one-dimensional optical lattice
Juha Javanainen, Otim Odong, Jerome C. Sanders
We investigate theoretically the stationary states of two bosons in a one-dimensional optical lattice within the Bose-Hubbard model. Starting from a finite lattice with periodic bo…
