We prove that the variance of the current across a characteristic is of order t in a stationary constant rate totally asymmetric zero range process, and that the diffusivity has order t. This is a step towards proving universality of this scaling behavior in the class of one-dimensional interacting systems with one conserved quantity and concave(More)
We study robustness under random attack for a class of networks, in which new nodes are given a spatial position and connect to existing vertices with a probability favouring short spatial distances and high degrees. In this model of a scale-free network with clustering one can independently tune the power law exponent τ > 2 of the degree distribution and a(More)

This review article discusses limit distributions and variance bounds for particle current in several dynamical stochastic systems of particles on the one-dimensional integer lattice: independent particles, independent particles in a random environment, the random average process, the asymmetric simple exclusion process, and a class of totally asymmetric(More)
In this paper we establish a connection between epidemic models on random networks with general infection times considered in [2] and first passage percolation. Using techniques developed in [6], when each vertex has infinite contagious periods, we extend results on the epidemic curve in [2] from bounded degree graphs to general sparse random graphs with(More)

These notes discuss limit distributions and variance bounds for particle current in several systems of particles on the one-dimensional integer lattice: independent random walks, independent random walks in a random environment, the random average process, the asymmetric simple exclusion process, and a class of zero range processes.
