A second-moment proof of quenched equals annealed for the Potts model on random regular graphs
Remco van der Hofstad, Kai-Chun Huang, Noela Müller +1
Ferromagnetic spin models on random regular graphs, such as the Ising and Potts models, have been studied extensively. Several equivalent variational and recursive representations…
Gaussian fluctuations of differential observables of stationary lattice fields
Fabio Coppini, Wioletta M. Ruszel
We study Gaussian fluctuations of differential observables of centered stationary random fields on the discrete -dimensional torus of mesh . Our main result is a Central Li…
Universal correlations in the Abelian sandpile model
Qiyu Liu, Jan-Niklas Herre, Prajit Baruah +4
We numerically study the bulk correlation functions in the two-dimensional Abelian sandpile model, aiming both to compare with the predictions of logarithmic conformal field theory…
Topological trapping in circular midpoint opinion dynamics
Annika Brockhaus, Wioletta M. Ruszel, Cristian Spitoni
We study a discrete-time asynchronous midpoint dynamics on the circle in which, at each step, a uniformly chosen neighboring pair moves to the midpoint along the shortest arc. Alth…
Topology, noise, and parallel updates in a model of circular opinion dynamics
Wioletta M. Ruszel, Cristian Spitoni
We study a circular opinion dynamics model with local midpoint interactions, extended to allow parallel updates of multiple sites. On a ring, the dynamics admits twisted states ass…
Central limit theorems for non-linear functionals of Gaussian fields via Wiener chaos decomposition
Fabio Coppini, Wioletta M. Ruszel
We review and present some known results for non-linear functionals of Gaussian variables in the context of discrete Gaussian fields defined on the dimensional lattice. Our mai…
