Laplacian growth is the study of interfaces that move in proportion to harmonic measure. Physically, it arises in fluid flow and electrical problems involving a moving boundary. We survey progress over the last decade on discrete models of (internal) Laplacian growth, including the abelian sandpile, internal DLA, rotor aggregation, and the scaling limits of these models on the lattice Z^d as the mesh size goes to zero. These models provide a window into the tools of discrete potential theory…

Laplacian growth and sandpiles on the Sierpiński gasket: limit shape universality and exact solutions
We establish quantitative spherical shape theorems for rotor-router aggregation and abelian sandpile growth on the graphical Sierpinski gasket ($SG$) when particles are launched from the corner
My title
The main purpose of the present paper is to establish a link between quadrature surfaces (potential theoretic concept) and sandpile dynamics (Laplacian growth models). For this aim, we introduce a
Tropical curves in sandpile models
A sandpile is a cellular automata on a subgraph $\Omega_h$ of ${h}\mathbb Z^2$ which evolves by the toppling rule: if the number of grains at a vertex is at least four, then it sends one grain to
The divisible sandpile model is a growth model on graphs that was introduced by Levine and Peres [Strong spherical asymptotics for rotor-router aggregation and the divisible sandpile, Potential Anal.
Odometers of Divisible Sandpile Models: Scaling Limits, iDLA and Obstacle Problems. A Survey
The divisible sandpile model is a fixed-energy continuous counterpart of the Abelian sandpile model. We start with a random initial configuration and redistribute mass deterministically. Under
Averaging Principle and Shape Theorem for a Growth Model with Memory
We present a general approach to study a class of random growth models in $n$-dimensional Euclidean space. These models are designed to capture basic growth features which are expected to manifest at
Non-Archimedean Coulomb gases
This article aims to study the Coulomb gas model over the $d$-dimensional $p$-adic space. We establish the existence of equilibria measures and the $\Gamma$-limit for the Coulomb energy functional
Sandpile toppling on Penrose tilings: identity and isotropic dynamics
We present experiments of sandpiles on grids (square, triangular, hexagonal) and Penrose tilings. The challenging part is to program such simulator; and our javacript code is available online, ready
Perfect boundaries in rotor-router aggregation on cylinders
We study a rotor-router version of the internal diffusion-limited aggregation introduced by J.Propp. The existing estimations of boundary fluctuations of the aggregation cluster show that they grow
A shape theorem for exploding sandpiles
We study scaling limits of exploding Abelian sandpiles using ideas from percolation and front propagation in random media. We establish sufficient conditions under which a limit shape exists and show


From logarithmic to subdiffusive polynomial fluctuations for internal DLA and related growth models
We consider a cluster growth model on Zd, called internal diffusion limited aggregation (internal DLA). In this model, random walks start at the origin, one at a time, and stop moving when reaching a
Scaling limits for internal aggregation models with multiple sources
We study the scaling limits of three different aggregation models on ℤd: internal DLA, in which particles perform random walks until reaching an unoccupied site; the rotor-router model, in which
Convergence of the Abelian sandpile
The Abelian sandpile growth model is a diffusion process for configurations of chips placed on vertices of the integer lattice $\mathbb{Z}^d$, in which sites with at least 2d chips {\em topple},
Growth Rates and Explosions in Sandpiles
We study the abelian sandpile growth model, where n particles are added at the origin on a stable background configuration in ℤd. Any site with at least 2d particles then topples by sending one
Height variables in the Abelian sandpile model: Scaling fields and correlations
We compute the lattice 1-site probabilities, on the upper half-plane, of the four height variables in the two-dimensional Abelian sandpile model. We find their exact scaling form when the insertion
Hele Shaw flows with a free boundary produced by the injection of fluid into a narrow channel
A blob of Newtonian fluid is sandwiched in the narrow gap between two plane parallel surfaces so that, a t some initial instant, its plan-view occupies a simply connected domain D 0 . Further fluid,
Stabilizability and percolation in the infinite volume sandpile model
We study the sandpile model in infinite volume on Z d . In particular, we are interested in the question whether or not initial configurations, chosen according to a stationary measure μ, are
Sublogarithmic fluctuations for internal DLA
We consider internal diffusion limited aggregation in dimension larger than or equal to two. This is a random cluster growth model, where random walks start at the origin of the d-dimensional
Strong Spherical Asymptotics for Rotor-Router Aggregation and the Divisible Sandpile
The rotor-router model is a deterministic analogue of random walk. It can be used to define a deterministic growth model analogous to internal DLA. We prove that the asymptotic shape of this model is
Infinite Volume Limit for the Stationary Distribution of Abelian Sandpile Models
We study the stationary distribution of the standard Abelian sandpile model in the box Λn = [-n, n]d ∩ ℤd for d≥ 2. We show that as n→ ∞, the finite volume stationary distributions weakly converge to
