In ballistic deposition (BD), (d+1)-dimensional particles fall sequentially at random towards an initially flat, large but bounded d-dimensional surface, and each particle sticks to the first point of contact. For both lattice and continuum BD, a law of large numbers in the thermodynamic limit establishes convergence of the mean height and surface width (sample standard deviation of the height) of the interface to constants h(t) and w(t), respectively, depending on time t. We show that h(t) is… 
Scaling limit of the heavy-tailed ballistic deposition model with $p$-sticking
Ballistic deposition is a classical model for interface growth in which unit blocks fall down vertically at random on the different sites of Z and stick to the interface at the first point of
A Membrane Computing Model for Ballistic Depositions
Ballistic Deposition was proposed by Vold [9] and Sutherland [8] as a model for colloidal aggregation. These early works were later extended to simulate the process of vapor deposition. In general,
Existence of stationary ballistic deposition on the infinite lattice
A BSTRACT . Ballistic deposition is one of the many models of interface growth that are believed to be in the KPZ universality class, but have so far proved to be largely intractable mathematically.
Superconcentration in surface growth
Height functions of growing random surfaces are often conjectured to be superconcentrated, meaning that their variances grow sublinearly in time. This article introduces a new concept — called
Random interface growth in a random environment: Renormalization group analysis of a simple model
We study the effects of turbulent mixing on the random growth of an interface in the problem of the deposition of a substance on a substrate. The growth is modeled by the well-known
On ballistic deposition process on a strip.
This work revisits the model of the ballistic deposition studied in [5] and proves several combinatorial properties of the random tree structure formed by the underlying stochastic process as well as certain intricate moments calculations.
The Kardar–Parisi–Zhang model of a random kinetic growth: effects of a randomly moving medium
The effects of a randomly moving environment on a randomly growing interface are studied by the field theoretic renormalization group. The kinetic roughening of an interface is described by the
Effects of turbulent environment on the surface roughening: The Kardar-Parisi-Zhang model coupled to the stochastic Navier–Stokes equation
The Kardar-Parisi-Zhang model of non-equilibrium critical behaviour (kinetic surface roughening) with turbulent motion of the environment taken into account is studied by the field theoretic
