Abstract The Sachdev–Ye–Kitaev (SYK) model is a strongly coupled, quantum many-body
system that is chaotic, nearly conformally invariant, and exactly solvable. This remarkable …

We generalize the recently discovered relationship between JT gravity and double-scaled
random matrix theory to the case that the boundary theory may have time-reversal symmetry …

The entanglement entropy of subsystems of typical eigenstates of quantum many-body
Hamiltonians has recently been conjectured to be a diagnostic of quantum chaos and …

We develop a theory of symmetry in open quantum systems. Using the operator-state
mapping, we characterize symmetry of Liouvillian superoperators for the open quantum …

In finite entropy systems, real-time partition functions do not decay to zero at late time.
Instead, assuming random matrix universality, suitable averages exhibit a growing" ramp" …

Spectral correlations are a powerful tool to study the dynamics of quantum many-body
systems. For Hermitian Hamiltonians, quantum chaotic motion is related to random matrix …

We propose the Sachdev-Ye-Kitaev Lindbladian as a paradigmatic solvable model of
dissipative many-body quantum chaos. It describes N strongly coupled Majorana fermions …

In this paper we further study the 1d Schwarzian theory, the universal low-energy limit of
Sachdev-Ye-Kitaev models, using the link with 2d Liouville theory. We provide a path …

A bstract Generalizing previous results for\(\mathcal {N}\)= 0 and\(\mathcal {N}\)= 1, we
analyze\(\mathcal {N}\)= 2 JT supergravity on asymptotically AdS 2 spaces with arbitrary …

Spectral rigidity in Hermitian quantum chaotic systems signals the presence of dynamical
universal features at timescales that can be much shorter than the Heisenberg time. We …
