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…
Controlling charge and spin currents through nonreciprocal dissipative processes
Catalin-Mihai Halati, Jean-Sébastien Bernier, Jean-Sébastien Bernier
We investigate the generation and control of both charge and spin currents via nonreciprocal dissipative mechanisms in a two-dimensional spinful fermionic atom quantum system with…
Master Equation for a Quantum Gas of Polarizable Particles in Cavities
Tom Schmit, Catalin-Mihai Halati, Tobias Donner +2
Quantum gases of atoms and molecules in optical cavities offer a formidable laboratory for studying the out-of-equilibrium dynamics of open quantum systems with long-range interact…
Steady state diagram of interacting fermionic atoms coupled to dissipative cavities
Luisa Tolle, Ameneh Sheikhan, Thierry Giamarchi +2
We investigate fermionic atoms subjected to an optical lattice and coupled to a high finesse optical cavity with photon losses. A transverse pump beam introduces a coupling between…
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…
Dissipative Generation of Currents by Nonreciprocal Local and Global Environments
Catalin-Mihai Halati
We investigate the mechanisms necessary for the stabilization of complex quantum correlations by exploring dissipative couplings to nonreciprocal reservoirs. We analyze the role of…
