We study the last-passage growth model on the planar integer lattice with exponential weights. With boundary conditions that represent the equilibrium exclusion process as seen from a particle right after its jump we prove that the variance of the last-passage time in a characteristic direction is of order $t^{2/3}$. With more general boundary conditions that include the rarefaction fan case we show that the last-passage time fluctuations are still of order $t^{1/3}$, and also that the…

Flats, spikes and crevices: the evolving shape of the inhomogeneous corner growth model

We study the macroscopic evolution of the growing cluster in the exactly solvable corner growth model with independent exponentially distributed waiting times. The rates of the exponentials are given

Limit shape and fluctuations for exactly solvable inhomogeneous corner growth models

We study a class of corner growth models in which the weights are either all exponentially or all geometrically distributed. The parameter of the distribution at site $(i, j)$ is $a_i+b_j$ in the

Diffusive scaling limit of the Busemann process in Last Passage Percolation

In exponential last passage percolation, we consider the rescaled Busemann process x 7→ N−1/2B 0,[xN ]e1 (x ∈ R), as a process parametrized by the scaled density ρ = 1/2+μ4N −1/2, and taking values

Optimal-order exit point bounds in exponential last-passage percolation via the coupling technique

We develop a new probabilistic method for deriving deviation estimates in directed planar polymer and percolation models. The key estimates are for exit points of geodesics as they cross transversal


We study the competition interface between two growing clusters in a growth model associated to last-passage percolation. When the initial unoccupied set is approximately a cone, we show that this

On the Geometry of the Last Passage Percolation Problem

We analyze the geometrical structure of the passage times in the last passage percolation model. Viewing the passage time as a piecewise linear function of the weights we determine the domains of the

Fluctuations of transverse increments in two-dimensional first passage percolation

We consider finite geodesics for first passage percolation (FPP) on $\mathbb{Z}^2$ with i.i.d.\ continuous passage times having exponential moments. As has been common in the literature, we assume

Order of the Variance in the Discrete Hammersley Process with Boundaries

We discuss the order of the variance on a lattice analogue of the Hammersley process with boundaries, for which the environment on each site has independent, Bernoulli distributed values. The last

KPZ-type fluctuation bounds for interacting diffusions in equilibrium

We study the fluctuations in equilibrium of a class of Brownian motions interacting through a potential. For a certain choice of exponential potential, the distribution of the system coincides with



Scaling Limit for the Space-Time Covariance of the Stationary Totally Asymmetric Simple Exclusion Process

The totally asymmetric simple exclusion process (TASEP) on the one-dimensional lattice with the Bernoulli ρ measure as initial conditions, 0<ρ<1, is stationary in space and time. Let Nt(j) be the

Existence of Hydrodynamics for the Totally Asymmetric Simple K-Exclusion Process

In a totally asymmetric simple K-exclusion process, particles take nearest-neighbor steps to the right on the lattice Z, under the constraint that each site contain at most K particles. We prove that

Second class particles as microscopic characteristics in totally asymmetric nearest-neighbor K-exclusion processes

Summary. We study aspects of the hydrodynamics of one-dimensional totally asym- metric K-exclusion, building on the hydrodynamic limit of Seppalainen (1999). We prove that the weak solution chosen by

Competition interfaces and second class particles

The one-dimensional nearest-neighbor totally asymmetric simple exclusion process can be constructed in the same space as a last-passage percolation model in Z 2 . We show that the trajectory of a

Roughening and inclination of competition interfaces.

It is demonstrated that a phase transition occurs for the asymptotic inclination of this interface when the final macroscopic shape goes from curved to noncurved, and that the flat case (stationary growth) is a critical point for the fluctuations.
