Collective Enhancement and Suppression of Excitation Decay in Optical Lattices
Hashem Zoubi, Helmut Ritsch
We calculate radiative lifetimes of collective electronic excitations of atoms in an infinite one dimensional lattice. The translational symmetry along the lattice restricts the ph…

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…
