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…
Josephson dynamics for coupled polariton modes under the atom-field interaction in the cavity
A. P. Alodjants, S. M. Arakelian, S. N. Bagayev +2
We consider a new approach to the problem of Bose-Einstein condensation (BEC) of polaritons for atom-field interaction under the strong coupling regime in the cavity. We investigat…
Quantum state of an injected TROPO above threshold : purity, Glauber function and photon number distribution
Tania Golubeva, Yuri Golubev, Claude Fabre +1
In this paper we investigate several properties of the full signal-idler-pump mode quantum state generated by a triply resonant non-degenerate Optical Parametric Oscillator operati…
Quantum memory for images - a quantum hologram
Denis V. Vasilyev, Ivan V. Sokolov, Eugene S. Polzik
Matter-light quantum interface and quantum memory for light are important ingredients of quantum information protocols, such as quantum networks, distributed quantum computation, e…
Light scattering from ultracold atoms in optical lattices as an optical probe of quantum statistics
Igor B. Mekhov, Christoph Maschler, Helmut Ritsch
We study off-resonant collective light scattering from ultracold atoms trapped in an optical lattice. Scattering from different atomic quantum states creates different quantum stat…
Probing quantum phases of ultracold atoms in optical lattices by transmission spectra in cavity QED
Igor. B. Mekhov, Christoph Maschler, Helmut Ritsch
Studies of ultracold atoms in optical lattices link various disciplines, providing a playground where fundamental quantum many-body concepts, formulated in condensed-matter physics…
