Modeling interacting dynamic networks: III. Extraordinary properties in a population of extreme introverts and extroverts

Autor: Liu, Wenjia, Greil, Florian, Bassler, Kevin E., Schmittmann, Beate, Zia, Royce K. P.

Recently, we introduced dynamic networks with preferred degrees, showing that interesting properties are present in a single, homogeneous system as well as one with two interacting networks. While simulations are readily performed, analytic studies a

Modeling interacting dynamic networks: I. Preferred degree networks and their characteristics

Autor: Liu, Wenjia, Jolad, Shivakumar, Schmittmann, Beate, Zia, R. K. P.

We study a simple model of dynamic networks, characterized by a set preferred degree, $\kappa$. Each node with degree $k$ attempts to maintain its $\kappa$ and will add (cut) a link with probability $w(k;\kappa)$ ($1-w(k;\kappa)$). As a starting poin

Anomalous nucleation far from equilibrium

Autor: Georgiev, Ivan T., Schmittmann, Beate, Zia, Royce K. P.

Publikováno v: Physical Review Letters 94, 115701-1 -- 4 (2005)

We present precision Monte Carlo data and analytic arguments for an asymmetric exclusion process, involving two species of particles driven in opposite directions on a $2 \times L$ lattice. We propose a scenario which resolves a stark discrepancy bet

Bond percolation of polymers

Autor: Gopalakrishnan, Manoj, Schmittmann, Beate, Zia, R. K. P.

Publikováno v: J. Phys. A 37(29)L337-L343 (2004)

We study bond percolation of $N$ non-interacting Gaussian polymers of $\ell$ segments on a 2D square lattice of size $L$ with reflecting boundaries. Through simulations, we find the fraction of configurations displaying {\em no} connected cluster whi

Report

Universal aspects of vacancy-mediated disordering dynamics: the effect of external fields

Autor: Triampo, Wannapong, Aspelmeier, Timo, Schmittmann, Beate

We investigate the disordering of an initially phase-segregated binary alloy, due to a highly mobile defect which couples to an electric or gravitational field. Using both mean-field and Monte Carlo methods, we show that the late stages of this proce
