Phases, instabilities and excitations in a two-component lattice model with photon-mediated interactions
Leon Carl, Rodrigo Rosa-Medina, Sebastian D. Huber +3
Engineering long-range interacting spin systems with ultra cold atoms offers the possibility to explore exotic magnetically ordered phases in strongly-correlated scenarios. Quantum…
Continuous feedback on a quantum gas coupled to an optical cavity
Katrin Kroeger, Nishant Dogra, Rodrigo Rosa-Medina +4
We present an active feedback scheme acting continuously on the state of a quantum gas dispersively coupled to a high-finesse optical cavity. The quantum gas is subject to a transv…
Dissipation Induced Structural Instability and Chiral Dynamics in a Quantum Gas
Nishant Dogra, Manuele Landini, Katrin Kroeger +3
Dissipative and unitary processes define the evolution of a many-body system. Their interplay gives rise to dynamical phase transitions and can lead to instabilities. We discovered…
Formation of a spin texture in a quantum gas coupled to a cavity
M. Landini, N. Dogra, K. Kroeger +3
We observe cavity mediated spin-dependent interactions in an off-resonantly driven multi-level atomic Bose-Einstein condensate that is strongly coupled to an optical cavity. Applyi…
