Ageing phenomena are observed in a large variety of dynamical systems exhibiting a slow relaxation from a non-equilibrium initial state. Ageing can be characterised in terms of the linear response R(t,s) at time t to a local perturbation at time s<t. Usually one distinguishes two dynamical regimes, namely, the quasi-stationary regime, where the response is translationally invariant in time, and the ageing regime, where this invariance is broken. In general these two regimes are separate in the…

On the predictive power of local scale invariance
Local scale invariance (LSI) is a theory for anisotropic critical phenomena designed in the spirit of conformal invariance. For a given representation of its generators this leads to non-trivial
Local persistence in the directed percolation universality class
We revisit the problem of local persistence in directed percolation, reporting improved estimates of the persistence exponent in 1+1 dimensions, discovering strong corrections to scaling in higher


Ageing, dynamical scaling and its extensions in many-particle systems without detailed balance
Recent studies on the phenomenology of ageing in certain many-particle systems which are at a critical point of their non-equilibrium steady states are reviewed. Examples include the contact process,
Universality classes in nonequilibrium lattice systems
This work is designed to overview our present knowledge about universality classes occurring in nonequilibrium systems defined on regular lattices. In the first section I summarize the most important
Non-equilibrium dynamics of simple spherical spin models
Abstract:We investigate the non-equilibrium dynamics of spherical spin models with two-spin interactions. For the exactly solvable models of the d-dimensional spherical ferromagnet and the spherical
Aging in ferromagnetic systems at criticality near four dimensions.
We study the off-equilibrium response and correlation functions and the corresponding fluctuation-dissipation ratio for a purely dissipative relaxation of an O(N) symmetric vector model (model A)
Test of local scale invariance from the direct measurement of the response function in the Ising model quenched to and below T(C).
The measurement of the response function in the kinetic Ising model with Glauber dynamics quenched to T(C) in d=4, where Gaussian behavior is expected to apply, supports the idea that local scale invariance might miss to capture the non-Gaussian features of the dynamics.
Non-equilibrium critical phenomena and phase transitions into absorbing states
This review addresses recent developments in non-equilibrium statistical physics. Focusing on phase transitions from fluctuating phases into absorbing states, the universality class of directed
Is local scale invariance a generic property of ageing phenomena
It is shown by means of numerical simulations that, in contradiction to recent claims by Enss et al (2004 J. Phys. A: Math. Gen. 37 10479), the autoresponse function of the critical (1+1)-dimensional
Local scale invariance as dynamical space-time symmetry in phase-ordering kinetics.
The scaling functions of the spatiotemporal response of coarsening systems are consistent with the prediction of local scale invariance, thereby suggesting the extension of dynamical scaling to space-time dynamical symmetry.
