Critical ageing of Ising ferromagnets relaxing from an ordered state

P Calabrese, A Gambassi… - Journal of Statistical …, 2006 - iopscience.iop.org
We investigate the nonequilibrium behaviour of the d-dimensional Ising model with purely
dissipative dynamics during its critical relaxation from a magnetized initial configuration. The …

Conjugate field and fluctuation-dissipation relation for the dynamic phase transition in the two-dimensional kinetic Ising model

DT Robb, PA Rikvold, A Berger, MA Novotny - Physical Review E—Statistical …, 2007 - APS
The two-dimensional kinetic Ising model, when exposed to an oscillating applied magnetic
field, has been shown to exhibit a nonequilibrium, second-order dynamic phase transition …

Intensive thermodynamic parameters in nonequilibrium systems

E Bertin, K Martens, O Dauchot, M Droz - Physical Review E—Statistical …, 2007 - APS
Considering a broad class of steady-state nonequilibrium systems for which some additive
quantities are conserved by the dynamics, we introduce from a statistical approach intensive …

Definition and relevance of nonequilibrium intensive thermodynamic parameters

E Bertin, O Dauchot, M Droz - Physical review letters, 2006 - APS
We show that intensive thermodynamic parameters associated to additive conserved
quantities can be naturally defined from a statistical approach in far-from-equilibrium steady …

Opinion formation model for markets with a social temperature and fear

Ageing phenomena without detailed balance: the contact process

T Enss, M Henkel, A Picone… - Journal of Physics A …, 2004 - iopscience.iop.org
