Excitons and cavity polaritons for ultracold atoms in an optical lattice
Hashem Zoubi, Helmut Ritsch
We study the resonant electronic excitation dynamics for ultracold atoms trapped in a deep optical lattice prepared in a Mott insulator state. Excitons in these artificial crystals…

Exciton-Polariton scattering for defect detection in cold atom Optical Lattices
Hashem Zoubi, Helmut Ritsch
We study the effect of defects in the Mott insulator phase of ultracold atoms in an optical lattice on the dynamics of resonant excitations. Defects, which can either be empty site…

Bright and dark excitons in an atom--pair filled optical lattice within a cavity
Hashem Zoubi, Helmut Ritsch
We study electronic excitations of a degenerate gas of atoms trapped in pairs in an optical lattice. Local dipole-dipole interactions produce a long lived antisymmetric and a short…
