Some recent progress in singular stochastic partial differential equations

I Corwin, H Shen - Bulletin of the American Mathematical Society, 2020 - ams.org
Stochastic partial differential equations are ubiquitous in mathematical modeling. Yet, many
such equations are too singular to admit classical treatment. In this article we review some …

Universal Kardar-Parisi-Zhang dynamics in integrable quantum systems

B Ye, F Machado, J Kemp, RB Hutson, NY Yao - Physical Review Letters, 2022 - APS
Although the Bethe ansatz solution of the spin-1/2 Heisenberg model dates back nearly a
century, the anomalous nature of its high-temperature transport dynamics has only recently …

Coloured stochastic vertex models and their spectral theory

A Borodin, M Wheeler - arxiv preprint arxiv:1808.01866, 2018 - arxiv.org
This work is dedicated to $\mathfrak {sl} _ {n+ 1} $-related integrable stochastic vertex
models; we call such models coloured. We prove several results about these models, which …

KPZ equation limit of sticky Brownian motion

S Das, H Drillick, S Parekh - Journal of Functional Analysis, 2024 - Elsevier
We consider the motion of a particle under a continuum random environment whose
distribution is given by the Howitt-Warren flow. In the moderate deviation regime, we …

Lower tail large deviations of the stochastic six vertex model

S Das, Y Liao, M Mucciconi - arxiv preprint arxiv:2407.08530, 2024 - arxiv.org
In this paper, we study lower tail probabilities of the height function $\mathfrak {h}(M, N) $ of
the stochastic six-vertex model. We introduce a novel combinatorial approach to …

Shift‐invariance for vertex models and polymers

A Borodin, V Gorin, M Wheeler - Proceedings of the London …, 2022 - Wiley Online Library
We establish a symmetry in a variety of integrable stochastic systems: certain multi‐point
distributions of natural observables are unchanged under a shift of a subset of observation …

The stochastic heat equation with multiplicative Lévy noise: Existence, moments, and intermittency

Q Berger, C Chong, H Lacoin - Communications in Mathematical Physics, 2023 - Springer
We study the stochastic heat equation (SHE)∂ tu= 1 2 Δ u+ β u ξ driven by a multiplicative
Lévy noise ξ with positive jumps and coupling constant β> 0, in arbitrary dimension d≥ 1 …

Color-position symmetry in interacting particle systems

A Borodin, A Bufetov - The Annals of Probability, 2021 - JSTOR
We prove a color-position symmetry for a class of ASEP-like interacting particle systems with
discrete time on the one-dimensional lattice. The full space-time inhomogeneity of our …

Lyapunov exponents of the SHE under general initial data

P Ghosal, Y Lin - Annales de l'Institut Henri Poincare (B) …, 2023 - projecteuclid.org
Abstract We consider the (1+ 1)-dimensional stochastic heat equation (SHE) with
multiplicative white noise and the Cole-Hopf solution of the Kardar–Parisi–Zhang (KPZ) …
