Ising metamagnets in thin film geometry: Equilibrium properties
(American Physical Society, 2011-10-17)
Artificial antiferromagnets and synthetic metamagnets have attracted much attention recently due to their potential for many different applications. Under some simplifying assumptions, these systems can be modeled by thin ...
Phenomenology of aging in the Kardar-Parisi-Zhang equation
(American Physical Society, 2012-03-27)
We study aging during surface growth processes described by the one-dimensional Kardar-Parisi-Zhang equation. Starting from a flat initial state, the systems undergo simple aging in both correlators and linear responses, ...
Dynamic phase transition in the three-dimensional kinetic Ising model in an oscillating field
(American Physical Society, 2013-03-20)
Using numerical simulations, we investigate the properties of the dynamic phase transition that is encountered in the three-dimensional Ising model subjected to a periodically oscillating magnetic field. The values of the ...
Nonequilibrium relaxation and aging scaling of the Coulomb and Bose glass
(Amer Physical Soc, 2014-09-11)
Entropy production in nonequilibrium steady states: A different approach and an exactly solvable canonical model
(American Physical Society, 2011-07-12)
We discuss entropy production in nonequilibrium steady states by focusing on paths obtained by sampling at regular (small) intervals, instead of sampling on each change of the system's state. This allows us to directly ...
Field-theory approaches to nonequilibrium dynamics
(Springer-Verlag Berlin, 2007-01-01)
It is explained how field-theoretic methods and the dynamic renormalisation group (RG) can be applied to study the universal scaling properties of systems that either undergo a continuous phase transition or display generic ...

Stochastic population oscillations in spatial predator-prey models

Nonequilibrium Relaxation and Critical Aging for Driven Ising Lattice Gases
(American Physical Society, 2012-03-13)
We employ Monte Carlo simulations to study the nonequilibrium relaxation of driven Ising lattice gases in two dimensions. Whereas the temporal scaling of the density autocorrelation function in the nonequilibrium steady ...
Aging processes in systems with anomalous slow dynamics
(American Physical Society, 2013-01-14)
Recently, different numerical studies of coarsening in disordered systems have shown the existence of a crossover from an initial, transient, power-law domain growth to a slower, presumably logarithmic, growth. However, ...
