Twin stimulated amplification of light and matter waves in an atom-photon pair laser
Thomas Salzburger, Helmut Ritsch
We consider ultracold atoms in a far detuned optical lattice orientated across a high-Q optical resonator. Applying an external driving laser to the atoms, which is red detuned fro…
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…
Anyonic interferometry and protected memories in atomic spin lattices
Liang Jiang, Gavin K. Brennen, Alexey V. Gorshkov +5
Strongly correlated quantum systems can exhibit exotic behavior called topological order which is characterized by non-local correlations that depend on the system topology. Such s…
Collective spin systems in dispersive optical cavity QED: Quantum phase transitions and entanglement
S. Morrison, A. S. Parkins
We propose a cavity QED setup which implements a dissipative Lipkin-Meshkov-Glick model -- an interacting collective spin system. By varying the external model parameters the syste…
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…
Ultracold atoms in optical lattices generated by quantized light fields
Christoph Maschler, Igor B. Mekhov, Helmut Ritsch
We study an ultracold gas of neutral atoms subject to the periodic optical potential generated by a high- cavity mode. In the limit of very low temperatures, cavity field and at…
