An introduction to the SYK model
V Rosenhaus - Journal of Physics A: Mathematical and …, 2019 - iopscience.iop.org
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 …

Black holes and random matrices
A bstract We argue that the late time behavior of horizon fluctuations in large anti-de Sitter
(AdS) black holes is governed by the random matrix dynamics characteristic of quantum …

The soft mode in the Sachdev-Ye-Kitaev model and its gravity dual
A Kitaev, SJ Suh - Journal of High Energy Physics, 2018 - Springer
A bstract We give an exposition of the SYK model with several new results. A non-local
correction to the Schwarzian effective action is found. The same action is obtained by …

An SYK-like model without disorder
E Witten - Journal of Physics A: Mathematical and Theoretical, 2019 - iopscience.iop.org
Making use of known facts about'tensor models', it is possible to construct a quantum system
without quenched disorder that has the same large n limit for its correlation functions and …

Supersymmetric sachdev-ye-kitaev models
We discuss a supersymmetric generalization of the Sachdev-Ye-Kitaev (SYK) model. These
are quantum mechanical models involving N Majorana fermions. The supercharge is given …

Uncolored random tensors, melon diagrams, and the Sachdev-Ye-Kitaev models
Certain models with rank-3 tensor degrees of freedom have been shown by Gurau and
collaborators to possess a novel large N limit, where g 2 N 3 is held fixed. In this limit the …
