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 systems allows to apply the result to colored (or multi-species) ASEP and stochastic vertex models for a certain class of initial/boundary conditions, generalizing previous results of Amir-Angel-Valko and Borodin-Wheeler. We are also able to use the symmetry, together with previously known results for uncolored…

Mixing times for the TASEP in the maximal current phase
We study mixing times for the totally asymmetric simple exclusion process (TASEP) on a segment of size N with open boundaries. We focus on the maximal current phase, and prove that the mixing time is
Shift‐invariance for vertex models and polymers
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 points. The
Shock fluctuations in TASEP under a variety of time scalings
We consider the totally asymmetric simple exclusion process (TASEP) with two different initial conditions with shock discontinuities, made by block of fully packed particles. Initially a second class
Stochastic Fusion of Interacting Particle Systems and Duality Functions
We introduce a new method, which we call stochastic fusion, which takes an exclusion process and constructs an interacting particle systems in which more than one particle may occupy a lattice site.
TASEP with a moving wall
We consider a totally asymmetric simple exclusion on Z with the step initial condition, under the additional restriction that the first particle cannot cross a deterministally moving wall. We prove
Observables of Stochastic Colored Vertex Models and Local Relation
We study the stochastic colored six vertex (SC6V) model and its fusion. Our main result is an integral expression for natural observables of this model -- joint q-moments of height functions. This
TASEP fluctuations with soft-shock initial data
We consider the totally asymmetric simple exclusion process with \emph{soft-shock} initial particle density, which is a step function increasing in the direction of flow and the step size chosen
Symmetries of stochastic colored vertex models
Author(s): Galashin, Pavel | Abstract: 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
Simplified Forms of the Transition Probabilities of the Two-Species ASEP with Some Initial Orders of Particles
It has been known that the transition probability of the single species ASEP with N particles is expressed as a sum of N ! N -fold contour integrals which are related to permutations in the symmetric

Stochastic six-vertex model
We study the asymmetric six-vertex model in the quadrant with parameters on the stochastic line. We show that the random height function of the model converges to an explicit deterministic limit

We consider a new interacting particle system on the one-dimensional lattice that interpolates between TASEP and Toom's model: A particle cannot jump to the right if the neighboring site is occupied,

TLDR
It is proved that the dynamical scaling exponent for kinetic roughening is z=3/2 in 1+1 dimensions and diagonalize it using the Bethe ansatz and predict the large-scale asymptotic behavior of the vertical polarization correlations.

AbstractThe asymmetric simple exclusion process (ASEP) on a one-dimensional lattice is a system of particles which jump at ratesp and 1-p (herep > 1/2) to adjacent empty sites on their right and left
