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…
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…
Coupling of Electronic and Motional Dynamics in a Cold Atom Optical Lattice
Hashem Zoubi, Helmut Ritsch
We study the coupling of internal electronic excitations to vibrational modes of the external motion of ultracold atoms in an optical lattice. For different ground and excited stat…
