Dissipation-induced Sachdev-Ye-Kitaev physics in many-body cavity quantum electrodynamics
The research explores how dissipation, not inherent chaos, can create quantum chaos in many-body systems using cavity quantum electrodynamics (QED). It shows that both single-mode atomic decay and multimode photon loss lead to the same universal physics—open Sachdev-Ye Kitaev (SYK) model—proving that dissipation fundamentally generates this chaotic behavior from integrable starting points.
