Scattering and binding of different atomic species in a one-dimensional optical lattice
R. T. Piil, N. Nygaard, K. Molmer
The theory of scattering of atom pairs in a periodic potential is presented for the case of different atoms. When the scattering dynamics is restricted to the lowest Bloch band of…
Two-channel Feshbach physics in a structured continuum
N. Nygaard, R. Piil, K. Molmer
We analyze the scattering and bound state physics of a pair of atoms in a one-dimensional optical lattice interacting via a narrow Feshbach resonance. The lattice provides a struct…
Feshbach Molecules in a One-dimensional Optical Lattice
N. Nygaard, R. Piil, K. Molmer
We present the theory of a pair of atoms in a one-dimensional optical lattice interacting via a narrow Feshbach resonance. Using a two-channel description of the resonance, we deri…
Tunnelling couplings in discrete lattices, single particle band structure and eigenstates of interacting atom pairs
Rune Piil, Klaus Molmer
By adjusting the tunnelling couplings over longer than nearest neighbor distances it is possible in discrete lattice models to reproduce the properties of the lowest energy band of…
