Pauli crystal superradiance
Daniel Ortuño-Gonzalez, Rui Lin, Justyna Stefaniak +4
Pauli crystals are unique geometric structures of non-interacting fermions, resembling crystals, that emerge solely from Fermi statistics and confinement. Unlike genuine quantum cr…
Synchronization of Quasi-Particle Excitations in a Quantum Gas with Cavity-Mediated Interactions
Gabriele Natale, Alexander Baumgärtner, Justyna Stefaniak +5
Driven-dissipative quantum systems can undergo transitions from stationary to dynamical phases, reflecting the emergence of collective non-equilibrium behavior. We study such a tra…
Stability and decay of subradiant patterns in a quantum gas with photon-mediated interactions
Alexander Baumgärtner, Simon Hertlein, Tom Schmit +5
Metastability and its relaxation mechanisms challenge our understanding of the stability of quantum many-body systems, revealing a gap between the microscopic dynamics of the indiv…
Self-oscillating pump in a topological dissipative atom-cavity system
Davide Dreon, Alexander Baumgärtner, Xiangliang Li +3
Pumps are transport mechanisms in which direct currents result from a cyclic evolution of the potential. As Thouless has shown, the pumping process can have topological origins, wh…
P-band induced self-organization and dynamics with repulsively driven ultracold atoms in an optical cavity
P. Zupancic, D. Dreon, X. Li +6
We investigate a Bose-Einstein condensate strongly coupled to an optical cavity via a repulsive optical lattice. We detect a stable self-ordered phase in this regime, and show that…
Two-mode Dicke model from non-degenerate polarization modes
Andrea Morales, Davide Dreon, Xiangliang Li +4
We realize a non-degenerate two-mode Dicke model with competing interactions in a Bose-Einstein condensate (BEC) coupled to two orthogonal polarization modes of a single optical ca…
