Optical Properties of Collective Excitations for Finite Chains of Trapped Atoms
Hashem Zoubi, Helmut Ritsch
Resonant dipole-dipole interaction modifies the energy and decay rate of electronic excitations for finite one dimensional chains of ultracold atoms in an optical lattice. We show…
Coupling of polaritons to vibrational modes of ultracold atoms in an optical lattice
Hashem Zoubi, Helmut Ritsch
The coupling of internal electronic excitations to vibrational modes of the external motion of ultracold atoms in an optical lattice is studied here in using a perturbation expansi…
Collective Electronic Excitation Coupling between Planar Optical Lattices using Ewald's Method
Hashem Zoubi, Helmut Ritsch
Using Ewald's summation method we investigate collective electronic excitations (excitons) of ultracold atoms in parallel planar optical lattices including long range interactions.…
Lifetime and Emission Characteristics of Electronic Excitations in 2D Optical Lattices
Hashem Zoubi, Helmut Ritsch
Collective electronic excitations "excitons" in planar optical lattices exhibit strong modifications of the radiative damping rate and directional emission pattern as compared to a…
