Single molecular-excitation propagation in one-dimensional optical lattices

Exponential localization in one-dimensional quasiperiodic optical lattices

We investigate the localization properties of a one-dimensional bichromatic optical lattice in the tight binding regime, by discussing how exponentially localized states emerge upon changing the degree of commensurability. We also review the mapping onto the discrete Aubry-André model, and provide evidences on how the momentum distribution gets modified in the crossover from extended to exponen...

Resonant Feshbach scattering of fermions in one-dimensional optical lattices

We consider Feshbach scattering of fermions in a one-dimensional optical lattice. By formulating the scattering theory in the crystal momentum basis, one can exploit the lattice symmetry and factorize the scattering problem in terms of center-of-mass and relative momentum in the reduced Brillouin zone scheme. Within a single band approximation, we can tune the position of a Feshbach resonance w...

Free Expansion of Impenetrable Bosons on One-dimensional Optical Lattices

We review recent exact results for the free expansion of impenetrable bosons on onedimensional lattices, after switching off a confining potential. When the system is initially in a superfluid state, far from the regime in which the Mott-insulator appears in the middle of the trap, the momentum distribution of the expanding bosons rapidly approaches the momentum distribution of noninteracting f...
