We study the model of the totally asymmetric exclusion process with generalized update, which compared to the usual totally asymmetric exclusion process, has an additional parameter enhancing clustering of particles. We derive the exact multiparticle distributions of distances travelled by particles on the infinite lattice for two types of initial conditions: step and alternating ones. Two different scaling limits of the exact formulas are studied. Under the first scaling associated to Kardar… 



Generalizations of TASEP in Discrete and Continuous Inhomogeneous Space

We investigate a rich new class of exactly solvable particle systems generalizing the Totally Asymmetric Simple Exclusion Process (TASEP). Our particle systems can be thought of as new exactly

Emergence of jams in the generalized totally asymmetric simple exclusion process.

A crossover parameter is identified and the large deviation function for particle current is derived, which interpolates between the case considered by Derrida-Lebowitz and a single-particle diffusion.

Tracy-Widom limit of $q$-Hahn TASEP

We consider the $q$-Hahn TASEP which is a three-parameter family of discrete time interacting particle systems. The particles jump to the right independently according to a certain $q$-Binomial

Integral Formulas for the Asymmetric Simple Exclusion Process

In this paper we obtain general integral formulas for probabilities in the asymmetric simple exclusion process (ASEP) on the integer lattice $${\mathbb{Z}}$$ with nearest neighbor hopping rates p to

Universal exit probabilities in the TASEP

We study the joint exit probabilities of particles in the totally asymmetric simple exclusion process (TASEP) from space–time sets of a given form. We extend previous results on the space–time

Limit process of stationary TASEP near the characteristic line

The totally asymmetric simple exclusion process (TASEP) on\input amssym ${\Bbb Z}$ with the Bernoulli‐ρ measure as an initial condition, 0 < ρ < 1, is stationary. It is known that along the

The Kardar-Parisi-Zhang equation and universality class

Brownian motion is a continuum scaling limit for a wide class of random processes, and there has been great success in developing a theory for its properties (such as distribution functions or

Fluctuations for stationary q-TASEP

We consider the q-totally asymmetric simple exclusion process (q-TASEP) in the stationary regime and study the fluctuation of the position of a particle. We first observe that the problem can be

Matrix-product ansatz for the totally asymmetric simple exclusion process with a generalized update on a ring.

A quadratic algebra is constructed and an analytic expression for the finite-size pair correlation function is obtained in the limit of irreversible aggregation p[over ̃]→1, when the stationary configurations contain just one cluster.

Transition between Airy1 and Airy2 processes and TASEP fluctuations

In this paper the totally asymmetric simple exclusion process is considered, a model in the KPZ universality class, and its one‐point distribution is a new interpolation between GOE and GUE edge distributions.
