Entanglement of midspectrum eigenstates of chaotic many-body systems: Reasons for deviation from random ensembles

M Haque, PA McClarty, IM Khaymovich - Physical Review E, 2022 - APS
Eigenstates of local many-body interacting systems that are far from spectral edges are
thought to be ergodic and close to being random states. This is consistent with the …
