A model of randomly-coupled Pauli spins
Masanori Hanada, Antal Jevicki, Xianlong Liu +2
We construct a model of Pauli spin operators with all-to-all 4-local interactions by replacing Majorana fermions in the SYK model with spin operators. Equivalently, we replace ferm…
Correlated Disorder in the SYK model
Pak Hang Chris Lau, Chen-Te Ma, Jeff Murugan +1
We study the SYK model of Majorana fermions with random quadratic interactions through a detailed spectral analysis and by coupling the model to 2- and 4-point sources. I…
Randomness and Chaos in Qubit Models
Pak Hang Chris Lau, Chen-Te Ma, Jeff Murugan +1
We introduce randomness into a class of integrable models and study the spectral form factor as a diagnostic to distinguish between randomness and chaos. Spectral form factors exhi…
Effective Hopping in Holographic Bose and Fermi-Hubbard Models
Mitsutoshi Fujita, Rene Meyer, Sumiran Pujari +1
In this paper, we analyze a proposed gravity dual to a Bose-Hubbard model, as well as construct a holographic dual of a Fermi-Hubbard model from D-branes in string…
Onset of Random Matrix Behavior in Scrambling Systems
Hrant Gharibyan, Masanori Hanada, Stephen H. Shenker +1
The fine grained energy spectrum of quantum chaotic systems is widely believed to be described by random matrix statistics. A basic scale in such a system is the energy range over…
Many-Body Localization in a finite-range Sachdev-Ye-Kitaev model
Antonio M. García-García, Masaki Tezuka
We study the level statistics of a generalized Sachdev-Ye-Kitaev (SYK) model with two-body and one-body random interactions of finite range by exact diagonalization. Tuning the ran…
Universality in Chaos: Lyapunov Spectrum and Random Matrix Theory
Masanori Hanada, Hidehiko Shimada, Masaki Tezuka
We propose the existence of a new universality in classical chaotic systems when the number of degrees of freedom is large: the statistical property of the Lyapunov spectrum is des…
Black Holes and Random Matrices
Jordan S. Cotler, Guy Gur-Ari, Masanori Hanada +6
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 chaotic s…
