K Matetski, J Quastel, D Remenik - Acta Mathematica, 2021 - projecteuclid.org
An explicit Fredholm determinant formula is derived for the multipoint distribution of the
height function of the totally asymmetric simple exclusion process (TASEP) with arbitrary …

Scaling limit of the colored ASEP and stochastic six-vertex models

A Aggarwal, I Corwin, M Hegde - arxiv preprint arxiv:2403.01341, 2024 - arxiv.org
We consider the colored asymmetric simple exclusion process (ASEP) and stochastic six
vertex (S6V) model with fully packed initial conditions; the states of these models can be …

A Aggarwal, A Borodin, M Wheeler - Communications of the American …, 2023 - ams.org
In this text we introduce and analyze families of symmetric functions arising as partition
functions for colored fermionic vertex models associated with the quantized affine Lie …

Colored interacting particle systems on the ring: Stationary measures from yang-baxter equation

A Aggarwal, M Nicoletti, L Petrov - arxiv preprint arxiv:2309.11865, 2023 - arxiv.org
Recently, there has been much progress in understanding stationary measures for colored
(also called multi-species or multi-type) interacting particle systems, motivated by asymptotic …

Brownian bridge limit of path measures in the upper tail of KPZ models

S Ganguly, M Hegde, L Zhang - arxiv preprint arxiv:2311.12009, 2023 - arxiv.org
For models in the KPZ universality class, such as the zero temperature model of planar last
passage-percolation (LPP) and the positive temperature model of directed polymers, its …

Multitime distribution in discrete polynuclear growth

K Johansson, M Rahman - Communications on pure and …, 2021 - Wiley Online Library
We study the multitime distribution in a discrete polynuclear growth model or, equivalently, in
directed last‐passage percolation with geometric weights. A formula for the joint multitime …

Cutoff profile of ASEP on a segment

A Bufetov, P Nejjar - Probability Theory and Related Fields, 2022 - Springer
This paper studies the mixing behavior of the Asymmetric Simple Exclusion Process (ASEP)
on a segment of length N. Our main result is that for particle densities in (0, 1), the total …

Symmetries of stochastic colored vertex models

P Galashin - The Annals of Probability, 2021 - JSTOR
We discover a new property of the stochastic colored six-vertex model called flip-invariance.
We use it to show that for a given collection of observables of the model, any transformation …

Orthogonal polynomial duality and unitary symmetries of multi-species ASEP (q, θ) and higher-spin vertex models via∗-bialgebra structure of higher rank quantum …

C Franceschini, J Kuan, Z Zhou - Communications in Mathematical …, 2024 - Springer
We propose a general method to produce orthogonal polynomial dualities from the∗-
bialgebra structure of Drinfeld–Jimbo quantum groups. The∗-structure allows for the …
