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 …

Entanglement is one of the most important concepts in quantum physics. We review recent
progress in understanding the quantum entanglement in many-body systems using large-N …

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 …

A bstract Motivated by recent studies of the information paradox in (1+ 1)-D anti-de Sitter
spacetime with a bath described by a (1+ 1)-D conformal field theory, we study the dynamics …

In closed generic many-body systems, unitary evolution disperses local quantum information
into highly nonlocal objects, resulting in thermalization. Such a process is called information …

A bstract Inspired by the Hayden-Preskill protocol for black hole evaporation, we consider
the dynamics of a quantum many-body qudit system coupled to an external environment …

Recently, the steady states of non-unitary free fermion dynamics are found to exhibit novel
critical phases with power-law squared correlations and a logarithmic subsystem …

A bstract We study the spread of Rényi entropy between two halves of a Sachdev-Ye-Kitaev
(SYK) chain of Majorana fermions, prepared in a thermofield double (TFD) state. The SYK …

We construct a series of one-dimensional non-unitary dynamics consisting of both unitary
and imaginary evolutions based on the Sachdev-Ye-Kitaev model. Starting from a short …

A bstract In this work, we study the information scrambling and the entanglement dynamics
in the complex Brownian Sachdev-Ye-Kitaev (cBSYK) models, focusing on their …
