On the observation of decoherence with a movable mirror
R. Folman, J. Schmiedmayer, H. Ritsch
Following almost a century of debate on possible `independent of measurement' elements of reality, or `induced' elements of reality - originally invoked as an ad-hoc collapse postu…
Generalized mean-field approach to simulate large dissipative spin ensembles with long range interactions
S. Krämer, H. Ritsch
We simulate the collective dynamics in spin lattices with long range interactions and collective decay in one, two and three dimensions. Starting from a dynamical mean-field approa…
Optomechanics with molecules in a strongly pumped ring cavity
R. J. Schulze, C. Genes, H. Ritsch
Cavity cooling of an atom works best on a cyclic optical transition in the strong coupling regime near resonance, where small cavity photon numbers suffice for trapping and cooling…
Collective excitations and instability of an optical lattice due to unbalanced pumping
J. K. Asboth, H. Ritsch, P. Domokos
We solve self-consistently the coupled equations of motion for trapped particles and the field of a one-dimensional optical lattice. Optomechanical coupling creates long-range inte…
A realization of a quasi-random walk for atoms in time-dependent optical potentials
T. Hinkel, H. Ritsch, C. Genes
We consider the time dependent dynamics of an atom in a two-color pumped cavity, longitudinally through a side mirror and transversally via direct driving of the atomic dipole. The…
An optical kaleidoscope using a single atom
P. Horak, H. Ritsch, T. Fischer +4
A new method to track the motion of a single particle in the field of a high-finesse optical resonator is described. It exploits near-degenerate higher-order Gaussian cavity modes,…
