Abstract The Sachdev–Ye–Kitaev model and two-dimensional dilaton gravity have recently
been attracting increasing attention of the high-energy and condensed-matter physics …

We study a quantum-mechanical model proposed by Sachdev, Ye and Kitaev. The model
consists of N Majorana fermions with random interactions of a few fermions at a time. It it …

We present a hypothesis for the universal properties of operators evolving under
Hamiltonian dynamics in many-body systems. The hypothesis states that successive …

We study a two-dimensional dilaton gravity system, recently examined by Almheiri and
Polchinski, which describes near-extremal black holes, or more generally, nearly A d S 2 …

A bstract We investigate a dilaton gravity model in AdS 2 proposed by Almheiri and
Polchinski [1] and develop a 1d effective description in terms of a dynamical boundary time …

A bstract We obtain exact expressions for a general class of correlation functions in the 1D
quantum mechanical model described by the Schwarzian action, that arises as the low …

A bstract We continue the study of the Sachdev-Ye-Kitaev model in the Large N limit.
Following our formulation in terms of bi-local collective fields with dynamical …

We review recent developments encompassing the description of quantum chaos in
holography. We discuss the characterization of quantum chaos based on the late time …

A bstract We explore the implications of stable gravitational orbits around an AdS black hole
for the boundary conformal field theory. The orbits are long-lived states that eventually decay …

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 …
