Abstract We show that the proper inclusion of soft reparameterization modes in the Sachdev–Ye–Kitaev model of N randomly interacting Majorana fermions reduces its long-time behavior to that of Liouville quantum mechanics. As a result, all zero temperature correlation functions decay with the universal exponent ∝ τ − 3 / 2 for times larger than the inverse single particle level spacing τ ≫ N ln ⁡ N . In the particular case of the single particle Green function this behavior is manifestation of…

A Note on Sachdev-Ye-Kitaev Like Model without Random Coupling
We study a description of the large N limit of the Sachdev-Ye-Kitaev (SYK) model in terms of quantum mechanics without quenched disorder. Instead of random couplings, we introduce massive scalar
Disorder in the Sachdev–Ye–Kitaev model
Abstract We give qualitative arguments in support of the mesoscopic nature of the Sachdev–Ye–Kitaev (SYK) model in the regime with q 2 / N ≪ 1 with N Majorana particles coupled by antisymmetric and
Notes on the complex Sachdev-Ye-Kitaev model
We describe numerous properties of the Sachdev-Ye-Kitaev model for complex fermions with N  ≫ 1 flavors and a global U(1) charge. We provide a general definition of the charge in the ( G, Σ)

TLDR
Stability of the Sachdev-Ye-Kitaev (SYK_{4}) model with a large but finite number of fermions N with respect to a perturbation, quadratic in fermionic operators is studied and analytic perturbance theory in the amplitude of the SYK_{2} perturbations is developed.
Non-local reparametrization action in coupled Sachdev-Ye-Kitaev models
Abstract We continue the investigation of coupled Sachdev-Ye-Kitaev (SYK) models without Schwarzian action dominance. Like the original SYK, at large N and low energies these models have an
Conformality of 1/N corrections in Sachdev-Ye-Kitaev-like models
The Sachdev-Ye-Kitaev (SYK) model is a quantum-mechanical model of N Majorana fermions which displays a number of appealing features—solvability in the strong coupling regime, near-conformal
Decoherence and microscopic diffusion at the Sachdev-Ye-Kitaev model
Sachdev-Ye-Kitaev (SYK) or embedded random ensembles are models ofN fermions with random k-body interactions. They play an important role in understanding black hole dynamics, quantum chaos, and
Power-law out of time order correlation functions in the SYK model
We evaluate the finite temperature partition sum and correlation functions of the Sachdev–Ye–Kitaev (SYK) model. Starting from a recently proposed mapping of the SYK model onto Liouville quantum
Chaos in a classical limit of the Sachdev-Ye-Kitaev model
We study chaos in a classical limit of the Sachdev-Ye-Kitaev (SYK) model obtained in a suitably defined large-S limit. The low-temperature Lyapunov exponent is found to depend linearly on
Chaotic-Integrable Transition in the Sachdev-Ye-Kitaev Model.
TLDR
Analytically and numerically it is shown that a generalized SYK model with an additional one-body infinite-range random interaction is still quantum chaotic and retains most of its holographic features for a fixed value of the perturbation and sufficiently high temperature.
