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…

Singularity of solutions to singular SPDEs

Martin Hairer, Seiichiro Kusuoka, Hirotatsu Nagoji

Building on the notes [Hai17], we give a sufficient condition for the marginal distribution of the solution of singular SPDEs on the -dimensional torus to be singular with respe…

Stochastic quantization of the weighted exponential QFT

Seiichiro Kusuoka, Hirotatsu Nagoji

We consider the stochastic quantization equation associated with the weighted exponential quantum field model (or the Høegh-Krohn model) on the two dimensional torus. Unlike in th…

Nonequilibrium steady state in Lindblad dynamics for infinite quantum spin systems

Kenji Shimomura, Nagisa Hara, Seiichiro Kusuoka

We consider Lindblad dynamics of quantum spin systems on infinite lattices and define a nonequilibrium steady state (NESS) and a time-averaged nonequilibrium steady state (TANESS)…

Berry-Esseen bounds for large-time asymptotics of one-dimensional diffusion processes via Malliavin-Stein method

Seiichiro Kusuoka, Yuichi Shiozawa

We consider solutions of stochastic differential equations which diverge to infinity as the time parameter goes to infinity. If the coefficients converge as the spacial variable go…
