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…

Hilbert Space Diffusion in Systems with Approximate Symmetries
Rahel L. Baumgartner, Luca V. Delacrétaz, Pranjal Nayak +1
Random matrix theory (RMT) universality is the defining property of quantum mechanical chaotic systems, and can be probed by observables like the spectral form factor (SFF). In thi…
