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, and when jumping to the left it simply pushes all the neighbors that block its way. We prove that for flat and step initial conditions, the large time fluctuations of theheight function of the associated growth model along any space-like path are described by the Airy 1 and Airy 2 processes.

Large Time Asymptotics of Growth Models on Space-like Paths II: PNG and Parallel TASEP

We consider the polynuclear growth (PNG) model in 1+1 dimension with flat initial condition and no extra constraints. The joint distributions of surface height at finitely many points at a fixed time

Two Speed TASEP

We consider the TASEP on ℤ with two blocks of particles having different jump rates. We study the large time behavior of particles’ positions. It depends both on the jump rates and the region we

Discrete-time anisotropic KPZ growth of random surface in 2+1 dimensions

We study the discrete-time analog of the stochastic growth models on a system of interacting particles in 2+1 dimensions, which belong to the anisotropic KPZ class introduced in [1]. We consider the

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

On Time Correlations for KPZ Growth in One Dimension

Time correlations for KPZ growth in 1 + 1 dimensions are reconsidered. We discuss flat, curved, and stationary initial conditions and are interested in the covariance of the height as a function of

Fluctuations of TASEP on a Ring in Relaxation Time Scale

We consider the totally asymmetric simple exclusion process on a ring with flat and step initial conditions. We assume that the size of the ring and the number of particles tend to infinity

Finite GUE Distribution with Cut-Off at a Shock

We consider the totally asymmetric simple exclusion process with initial conditions generating a shock. The fluctuations of particle positions are asymptotically governed by the randomness around the

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

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.

Scale Invariance of the PNG Droplet and the Airy Process

We establish that the static height fluctuations of a particular growth model, the PNG droplet, converges upon proper rescaling to a limit process, which we call the Airy process A(y). The Airy
