Precision molecular spectroscopy for ground state transfer of molecular quantum gases
Johann G. Danzl, Manfred J. Mark, Elmar Haller +6
One possibility for the creation of ultracold, high-phase-space-density quantum gases of molecules in the rovibrational ground state relies on first associating weakly-bound molecu…
Strong magnetic coupling of an ultracold gas to a superconducting waveguide cavity
J. Verdu, H. Zoubi, Ch. Koller +3
Placing an ensemble of ultracold atoms in the near field of a superconducting coplanar waveguide resonator (CPWR) with one can achieve strong coupling between…
Polarization-Mixing in Optical Lattices with Uniaxial Anisotropy
Hashem Zoubi, Helmut Ritsch
We study optical excitations of an ultracold gas in an optical lattice in the Mott insulator case and with anisotropic properties. The anisotropy is induced by an oriented transiti…
Quantum Gas of Deeply Bound Ground State Molecules
Johann G. Danzl, Elmar Haller, Mattias Gustavsson +6
We create an ultracold dense quantum gas of ground state molecules bound by more than 1000 wavenumbers by stimulated two-photon transfer of molecules associated on a Feshbach reson…
QND measurements and state preparation in quantum gases by light detection
Igor B. Mekhov, Helmut Ritsch
We consider light scattering from ultracold atoms trapped in an optical lattice into a cavity. The measurement of photons leaking out the cavity provides a quantum nondemolition (Q…
Cavity nonlinear optics with few photons and ultracold quantum particles
András Vukics, Wolfgang Niedenzu, Helmut Ritsch
The light force on particles trapped in the field of a high-Q cavity mode depends on the quantum state of field and particle. Different photon numbers generate different optical po…
