Spontaneously ordered motion of self-propelled particles

Andras Czirok, H. Eugene Stanley, Tamas Vicsek

We study a biologically inspired, inherently non-equilibrium model consisting of self-propelled particles. In the model, particles move on a plane with a velocity of constant magni…

Smoothing a Rock by Chipping

P. L. Krapivsky, S. Redner

We investigate an idealized model for the size reduction and smoothing of a polygonal rock due to repeated chipping at corners. Each chip is sufficiently small so that only a singl…

Flows on Graphs with Random Capacities

T. Antal, P. L. Krapivsky

We investigate flows on graphs whose links have random capacities. For binary trees we derive the probability distribution for the maximal flow from the root to a leaf, and show th…

Transient Nucleation near the Mean-Field Spinodal

A. O. Schweiger, K. Barros, W. Klein

Nucleation is considered near the pseudospinodal in a one-dimensional model with a non-conserved order parameter and long-range interactions. For a sufficiently large system…

Condensates in Driven Aggregation Processes

E. Ben-Naim, P. L. Krapivsky

We investigate aggregation driven by mass injection. In this stochastic process, mass is added with constant rate r and clusters merge at a constant total rate 1, so that both the…

Scaling in Tournaments

E. Ben-Naim, S. Redner, F. Vazquez

We study a stochastic process that mimics single-game elimination tournaments. In our model, the outcome of each match is stochastic: the weaker player wins with upset probability…

The structure of fluctuations near mean-field critical points and spinodals and its implication for physical processes

W. Klein, Harvey Gould, Natali Gulbahce +2

We analyze the structure of fluctuations near critical points and spinodals in mean-field and near-mean-field systems. Unlike systems that are non-mean-field, for which a fluctuati…

Shot noise of interference between independent atomic systems

Anatoli Polkovnikov

We study shot (counting) noise of the amplitude of interference between independent atomic systems. In particular, for the two interfering systems the variance of the fringe amplit…

Dynamical arrest and replica symmetry breaking in attractive colloids

A. Velenich, A. Parola, L. Reatto

Within the Replica Symmetry Breaking (RSB) framework developed by M.Mezard and G.Parisi we investigate the occurrence of structural glass transitions in a model of fluid characteri…

DNA unzipping and the unbinding of directed polymers in a random media

Yariv Kafri, Anatoli Polkovnikov

We consider the unbinding of a directed polymer in a random media from a wall in dimensions and a simple one-dimensional model for DNA unzipping. Using the replica trick we…

Relationship between Fragility, Diffusive Directions and Energy Barriers in a Supercooled Liquid

Manuel I. Marques, H. Eugene Stanley

An analysis of diffusion in a supercooled liquid based solely in the density of diffusive directions and the value of energy barriers shows how the potential energy landscape (PEL)…

Weak Disorder in Fibonacci Sequences

E. Ben-Naim, P. L. Krapivsky

We study how weak disorder affects the growth of the Fibonacci series. We introduce a family of stochastic sequences that grow by the normal Fibonacci recursion with probability 1-…
