Fluctuation-Induced Bistability in the Dissipative Dynamics of Generic Cavity-Matter Quantum Systems
Luisa Tolle, Simon B. Jäger, Ameneh Sheikhan +2
We demonstrate that fluctuation-induced bistability is a robust and generic phenomenon in strongly interacting many-body systems with strong light-matter coupling. We identify a co…
From Light-Cone to Supersonic Propagation of Correlations by Competing Short- and Long-Range Couplings
Catalin-Mihai Halati, Ameneh Sheikhan, Giovanna Morigi +2
We investigate the dynamical spreading of correlations in many-body quantum systems with competing short- and global-range couplings. We monitor the non-equilibrium dynamics of the…
Fully Collective Superradiant Lasing with Vanishing Sensitivity to Cavity Length Vibrations
Jarrod T. Reilly, Simon B. Jäger, John Cooper +1
To date, realization of a continuous-wave active atomic clock has been elusive primarily due to parasitic heating from spontaneous emission while repumping the atoms. Here, we prop…
Engineering tunable decoherence-free subspaces with collective atom-cavity interactions
Lyryl H. C. Vaecairn, Jarrod T. Reilly, John Drew Wilson +2
We propose schemes to design and control a time-dependent decoherence-free subspace (DFS) in a dissipative atom-cavity system. These schemes use atoms with three internal energy le…
Spin self-organization in an optical cavity facilitated by inhomogeneous broadening
Marc Nairn, Luigi Giannelli, Giovanna Morigi +3
We study the onset of collective spin-self-organization in a thermal ensemble of driven two-level atoms confined in an optical cavity. The atoms spontaneously form a spin-pattern a…
