We study the $kappa$-color cyclic particle system on the one-dimensional integer lattice $mathbb{Z}$, first introduced by Bramson and Griffeath in cite{bramson1989flux}. In that paper they show that almost surely, every site changes its color infinitely often if $kappain {3,4}$ and only finitely many times if $kappage 5$. In addition, they conjecture that for $kappain {3,4}$ the system clusters, that is, for any pair of sites $x,y$, with probability tending to 1 as $ttoinfty$, $x$ and $y$ have the same color at time $t$. Here we prove that conjecture.
Families of three-body Hamiltonian systems in one dimension have been recently proved to be maximally superintegrable by interpreting them as one-body systems in the three-dimensional Euclidean space, examples are the Calogero, Wolfes and Tramblay Tu
We investigate the mean first passage time of an active Brownian particle in one dimension using numerical simulations. The activity in one dimension is modeled as a two state model; the particle moves with a constant propulsion strength but its orie
Let v, w be infinite 0-1 sequences, and m a positive integer. We say that w is m-embeddable in v, if there exists an increasing sequence n_{i} of integers with n_{0}=0, such that 0< n_{i} - n_{i-1} < m, w(i) = v(n_i) for all i > 0. Let X and Y be ind
We prove distributional convergence for a family of random processes on $mathbb{Z}$, which we call cooperative motions. The model generalizes the totally asymmetric hipster random walk introduced in [Addario-Berry, Cairns, Devroye, Kerriou and Mitche
We study the scaling limit of a large class of voter model perturbations in one dimension, including stochastic Potts models, to a universal limiting object, the continuum voter model perturbation. The perturbations can be described in terms of bulk
