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…
Pair scattering from time-modulated impurity in the Bose-Hubbard model
Neda Ahmadi, Ameneh Sheikhan, Corinna Kollath
We investigate scattering phenomena in a one-dimensional attractive Bose-Hubbard model with a time-periodically modulated impurity. We analyze both single-particle and pair (doublo…
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…
Fluctuation-Induced Bistability of Fermionic Atoms Coupled to a Dissipative Cavity
Luisa Tolle, Ameneh Sheikhan, Thierry Giamarchi +2
We investigate the steady state phase diagram of fermionic atoms subjected to an optical lattice and coupled to a high finesse optical cavity with photon losses. The coupling betwe…
Floquet-driven crossover from density-assisted tunneling to enhanced pair tunneling
Nick Klemmer, Janek Fleper, Valentin Jonas +4
We investigate the experimental control of pair tunneling in a double-well potential using Floquet engineering. We demonstrate a crossover from a regime with density-assisted tunne…
