Controlling many-body quantum chaos in a dissipative optical cavity
Filippo Ferrari, Francesca Orsi, Ekaterina Fedotova +4
Cavity quantum electrodynamics (QED) with ultracold fermions provides a promising platform for realizing many-body quantum chaos through disordered, photon-mediated long-range inte…
Fermi-pressure-assisted cavity superradiance in a mesoscopic Fermi gas
Francesca Orsi, Ekaterina Fedotova, Rohit Prasad Bhatt +3
We study the superradiant phase transition of a mesoscopic Fermi gas comprising between a few tens and a few thousand Li atoms in a high-finesse cavity across a wide range of d…
Quantum simulation of the Sachdev-Ye-Kitaev model using time-dependent disorder in optical cavities
Rahel Baumgartner, Pietro Pelliconi, Soumik Bandyopadhyay +5
The Sachdev--Ye--Kitaev (SYK) model is a paradigm for extreme quantum chaos, non-Fermi-liquid behavior, and holographic matter. Yet, the dense random all-to-all interactions that c…
Quantum simulation using Trotterized disorder Hamiltonians in a single-mode optical cavity
Rahel Lea Baumgartner, Pietro Pelliconi, Soumik Bandyopadhyay +4
All-to-all interacting and disordered many-body systems are notoriously hard to simulate on quantum platforms, as interactions are commonly mediated by auxiliary degrees of freedom…
Design and assembly of a cavity microscope with high numerical aperture for quantum simulations
Gaia Stella Bolognini, Zeyang Xue, Michael Alexander Eichenberger +5
We present the design and assembly of a cavity microscope for quantum simulations with ultracold atoms. The system integrates a high-finesse optical cavity with a pair of high-nume…
