Superradiant and Dark Exciton States in an Optical Lattice within a Cavity
Hashem Zoubi, Helmut Ritsch
We study ultracold atoms in a finite size one-dimensional optical lattice prepared in the Mott insulator phase and commonly coupled to a single cavity mode. Due to resonance dipole…
Quantum Phases of Ultracold Bosonic Atoms in two Bands of an Optical-Lattice coupled by a Cavity Field
Hashem Zoubi, Helmut Ritsch
We study the quantum phase transitions between superfluid and Mott insulator states for ultracold bosons occupying two bands of an optical lattice. The two atomic states are resona…
Coupling of Electronic and Motional Dynamics in a Cold Atom Optical Lattice
Hashem Zoubi, Helmut Ritsch
We study the coupling of internal electronic excitations to vibrational modes of the external motion of ultracold atoms in an optical lattice. For different ground and excited stat…
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…
