Relaxation at finite temperature in Fully-Frustrated Ising Models

Jean-Charles Walter, Christophe Chatelain

We consider by means of Monte Carlo simulations the relaxation in the paramagnetic phase of the anti-ferromagnetic Ising model on a triangular lattice and of a fully-frustrated Isi…

Model study on steady heat capacity in driven stochastic systems

Jiri Pesek, Eliran Boksenbojm, Karel Netocny

We explore two- and three-state Markov models driven out of thermal equilibrium by non-potential forces to demonstrate basic properties of the steady heat capacity based on the con…

Fractional Brownian motion and the critical dynamics of zipping polymers

Jean-Charles Walter, Alessandro Ferrantini, Enrico Carlon +1

We consider two complementary polymer strands of length attached by a common end monomer. The two strands bind through complementary monomers and at low temperatures form a dou…

Heat capacity in nonequilibrium steady states

Eliran Boksenbojm, Christian Maes, Karel Netocny +1

We show how to extend the concept of heat capacity to nonequilibrium systems. The main idea is to consider the excess heat released by an already dissipative system when slowly cha…

Equilibrium winding angle of a polymer around a bar

Jean-Charles Walter, Gerard Barkema, Enrico Carlon

The winding angle probability distribution of a planar self-avoiding walk has been known exactly since a long time: it has a gaussian shape with a variance growing as $<θ^2>\sim \l…

Spectra of sparse regular graphs with loops

F. L. Metz, I. Neri, D. Bollé

We derive exact equations that determine the spectra of undirected and directed sparsely connected regular graphs containing loops of arbitrary length. The implications of our resu…

Criterion for explosive percolation transitions on complex networks

H. Hooyberghs, B. Van Schaeybroeck

In a recent Letter, Friedman and Landsberg discussed the underlying mechanism of explosive phase transitions on complex networks [Phys. Rev. Lett. 103, 255701 (2009)]. This Brief R…

Saturation of front propagation in a reaction-diffusion process describing plasma damage in porous low-k materials

Soghra Safaverdi, Gerard T. Barkema, Eddy Kunnen +2

We propose a three-component reaction-diffusion system yielding an asymptotic logarithmic time-dependence for a moving interface. This is naturally related to a Stefan-problem for…

Monotone return to steady nonequilibrium

Christian Maes, Karel Netocny, Bram Wynants

We propose and analyze a new candidate Lyapunov function for relaxation towards general nonequilibrium steady states. The proposed functional is obtained from the large time asympt…

Nonequilibrium wetting transition in a nonthermal 2D Ising model

Jef Hooyberghs, Joseph O. Indekeu

Nonequilibrium wetting transitions are observed in Monte Carlo simulations of a kinetic spin system in the absence of a detailed balance condition with respect to an energy functio…

The modified Sutherland--Einstein relation for diffusive nonequilibria

Marco Baiesi, Christian Maes, Bram Wynants

There remains a useful relation between diffusion and mobility for a Langevin particle in a periodic medium subject to nonconservative forces. The usual fluctuation-dissipation rel…

Dynamical Rare event simulation techniques for equilibrium and non-equilibrium systems

Titus S. van Erp

I give an overview of rare event simulation techniques to generate dynamical pathways across high free energy barriers. The methods on which I will concentrate are the reactive flu…
