A quantitative replica-symmetric bound of Sherrington--Kirkpatrick model in the entire de Almeida--Thouless region

Seiichiro Kusuoka, Shuta Nakajima

We consider the Sherrington--Kirkpatrick model with inverse temperature and deterministic external field . Let be the replica-symmetric fixed point: $q=\mathbb E{\rm…

A note on Lata\la's argument in SK model

Seiichiro Kusuoka, Shuta Nakajima

In this note, we consider the Sherrington--Kirkpatrick model with deterministic external field. Let denote the solution of the replica-symmetric self-consistency equati…

Uniqueness of Replica-symmetric Saddle Point for Ising Perceptron

Shuta Nakajima

We study the replica-symmetric saddle point equations for the Ising perceptron with Gaussian disorder and margin . We prove that for each there is a critical cap…

Quantum Chaos, Thermalization, and Non-locality

Masataka Matsumoto, Shuta Nakajima, Masahiro Nozaki +1

In this paper, we numerically investigate whether quantum thermalization occurs during the time evolution induced by a non-local Hamiltonian whose spectra exhibit integrability. Th…
