Erdos-Renyi random graphs + forest fires = self-organized criticality
Rath, Balazs; Budapest University of Technology - Toth, Balint; Budapest University of Technology

Formato:	Peer-reviewed Article,
Enlaces:	We modify the usual Erdos-Renyi random graph evolution by letting connected clusters 'burn down' (i.e. fall apart to disconnected single sites) due to a Poisson flow of lightnings. In a range of the intensity of rate of lightnings the system…

Density fluctuations for a zero-range process on the percolation cluster
Goncalves, Patricia C.; CMAT - U. Minho - Jara, Milton D.; Paris Dauphine

Formato:	Peer-reviewed Article,
Enlaces:	We prove that the density fluctuations for a zero-range process evolving on the $d$-dimensional supercritical percolation cluster, with $d\geq{3}$, are given by a generalized Ornstein-Uhlenbeck process in the space of distributions $\mathscr{S}'(\mathbb{R}^d)$.

Central Limit Theorem for a Class of Linear Systems
Nagahata, Yukio; Osaka University - Yoshida, Nobuo; Kyoto University

Formato:	Peer-reviewed Article,
Enlaces:	We consider a class of interacting particle systems with values in $[0,∞)^{\mathbb{Z}^d}$, of which the binary contact path process is an example. For $d \geq 3$ and under a certain square integrability condition on the total number of the particles,…

Some two-dimensional finite energy percolation processes
Häggström, Olle; Chalmers University of Technology - Mester, Péter; Indiana University

Formato:	Peer-reviewed Article,
Enlaces:	Some examples of translation invariant site percolation processes on the $Z^2$ lattice are constructed, the most far-reaching example being one that satisfies uniform finite energy (meaning that the probability that a site is open given the status of all others…

The Time Constant Vanishes Only on the Percolation Cone in Directed First Passage Percolation
Zhang, Yu; University of Colorado

Formato:	Peer-reviewed Article,
Enlaces:	We consider the directed first passage percolation model on $\mathbb{Z}^2$. In this model, we assign independently to each edge $e$ a passage time $t(e)$ with a common distribution $F$. We denote by $\vec{T}(0,(r,\theta))$ the passage time from the origin to…

A limit theorem for particle current in the symmetric exclusion process
Vandenberg-Rodes, Alexander; UC Los Angeles

Formato:	Peer-reviewed Article,
Enlaces:	Using the recently discovered strong negative dependence properties of the symmetric exclusion process, we derive general conditions for when the normalized current of particles between regions converges to the Gaussian distribution. The main novelty is that the results do not…

Stochastic Domination for the Ising and Fuzzy Potts Models
Warfheimer, Marcus; Chalmers University of Technology and University of Gothenburg

Formato:	Peer-reviewed Article,
Enlaces:	We discuss various aspects concerning stochastic domination for the Ising model and the fuzzy Potts model. We begin by considering the Ising model on the homogeneous tree of degree $d$, $\mathbb{T}^d$. For given interaction parameters $J_1$, $J_2>0$ and external field…

Multitype Contact Process on Z: Extinction and Interface
Valesin, Daniel; École Polytechnique Fédérale de Lausanne

Formato:	Peer-reviewed Article,
Enlaces:	We consider a two-type contact process on the integers. Both types have equal finite range and supercritical infection rate. We show that a given type becomes extinct with probability 1 if and only if, in the initial configuration, it is…

Soft edge results for longest increasing paths on the planar lattice
Georgiou, Nicos; UW-Madison

Formato:	Peer-reviewed Article,
Enlaces:	For two-dimensional last-passage time models of weakly increasing paths, interesting scaling limits have been proved for points close the axis (the hard edge). For strictly increasing paths of Bernoulli($p$) marked sites, the relevant boundary is the line $y=px$. We call…

Formato:	Peer-reviewed Article
Enlaces:	Let $S_{n,k}$ denote the random geometric graph obtained by placing points inside a square of area $n$ according to a Poisson point process of intensity $1$ and joining each such point to the $k=k(n)$ points of the process nearest to…

Graphical representation of certain moment dualities and application to population models with balancing selection
Jansen, Sabine; Leiden University - Kurt, Noemi; TU Berlin

Formato:	Peer-reviewed Article
Enlaces:	We investigate dual mechanisms for interacting particle systems. Generalizing an approach of Alkemper and Hutzenthaler in the case of coalescing duals, we show that a simple linear transformation leads to a moment duality of suitably rescaled processes. More precisely, we…

The gaps between the sizes of large clusters in 2D critical percolation
van den Berg, Jacob; Centrum Wiskunde & Informatica - Conijn, Rene; VU University Amsterdam

Formato:	Peer-reviewed Article
Enlaces:	Consider critical bond percolation on a large $2 n \times 2 n$ box on the square lattice. It is well-known that the size (i.e. number of vertices) of the largest open cluster is, with high probability, of order $n^2 \pi(n)$, where $\pi(n)$ denotes…
