The relaxational dynamics of a (1 + 1)-dimensional directed polymer in random potential is studied by Monte Carlo simulations. A series of temperature quench experiments is performed changing waiting times . A clear crossover from quasi-equilibrium behaviour to off-equilibrium behaviour appears in the dynamical overlap function whose scaling properties are very similar to those found in the three-dimensional spin-glass model. In the part, the fluctuation dissipation theorem of the first kind… 
Dynamics of unbinding of polymers in a random medium
The aging effect on the dynamics of unbinding of a double stranded directed polymer in a random medium is studied by using the Monte Carlo dynamics of a lattice model in two dimensions and the overlap of the two strands is formulated.
Aging and relaxation dynamics in free-energy landscapes with multiple minima
Abstract We consider the stochastic dynamics of a system thermally relaxing in a free-energy landscape with multiple attractors, and show that lack of translational homogeneity in this landscape
Non-equilibrium dynamics of disordered systems: renormalization flow towards an ‘infinite disorder’ fixed point at large times
To describe the non-equilibrium dynamics of random systems, we have recently introduced (Monthus and Garel, 2008 J. Phys. A: Math. Theor. 41 255002) a 'strong disorder renormalization' (RG) procedure
Out-of-equilibrium relaxation of the Edwards–Wilkinson elastic line
We study the non-equilibrium relaxation of an elastic line described by the Edwards–Wilkinson equation. Although this model is the simplest representation of interface dynamics, we highlight that
Growing dynamical length, scaling, and heterogeneities in the 3D Edwards–Anderson model
We study numerically spatio-temporal fluctuations during the out-of-equilibrium relaxation of the three-dimensional Edwards–Anderson model. We focus on two issues. (1) The evolution of a growing
Langevin simulations of the out-of-equilibrium dynamics of vortex glasses in high-temperature superconductors
We study the relaxation dynamics of flux lines in dirty high-temperature superconductors using numerical simulations of a London-Langevin model of the interacting vortex lines. By analysing the
Non-equilibrium dynamics of polymers and interfaces in random media: conjecture ψ = ds/2 for the barrier exponent
We consider various random models (directed polymer, random ferromagnets, spin glasses) in their disorder-dominated phases, where the free-energy cost F(L) of an excitation of length L presents

Monte Carlo simulation on aging processes within one `pure state' of the SK spin-glass model
Monte Carlo simulations on the SK model have been done to investigate aging processes after a rapid quench from to the spin-glass phase. Taking care of time ranges of simulation, we examine time
Intermittent dynamics and aging in glassy systems
We discuss in details the so-called ‘aging’ phenomenon, which appears in a large variety of ‘glassy’ systems, including spin-glasses, polymers, or glassy liquids. Simple models accounting for this


On the glassy nature of random directed polymers in two dimensions
We study numerically directed polymers in a random potential in 1 + 1 dimensions. We introduce two copies of the polymer, coupled through a thermodynamic local interaction. We show that the system is

It is argued that the power-law distribution of large thermally active excitation is a consequence of the continuous statistical tilt'' symmetry of the directed polymer, the breaking of which gives rise to the large active excitations in a manner analogous to the appearance of Goldstone modes in pure systems with a broken continuous symmetry.

The properties of directed paths in random media are explored, with emphasis on the low-temperature phase, and it is argued that at fixed temperature, the possible states of a directed path in an infinite system with one end fixed are simply parametrized by its average orientation.
Analytical solution of the off-equilibrium dynamics of a long-range spin-glass model.
A functional Parisi-like order parameter is determined which plays a similar role for the dynamics to that played by the usual function for the statics in the spherical spin-glass model with p-spin interactions in the N-spin limit.
Nonequilibrium dynamics and aging in the three-dimensional Ising spin-glass model
The low temperature dynamics of the three-dimensional Ising spin-glass in zero field with a discrete bond distribution is investigated via MC simulations. The thermoremanent magnetization is found to
Weak ergodicity breaking and aging in disordered systems
We present a phenomenological model for the dynamics of disordered (complex) systems. We postulate that the lifetimes of the many metastable states are distributed according to a broad, power law
On the out-of-equilibrium relaxation of the Sherrington-Kirkpatrick model
Starting from a set of assumptions on the long-time limit behaviour of the nonequilibrium relaxation of mean-field models in the thermodynamic limit, we derive analytical results for the long-time
On the replica approach to random directed polymers in two dimensions
In this note we study directed polymers in a two dimensional random medium with short range noise using the replica approach. We find the predictions of the replica symmetric theory and we compare

Ageing phenomena in a spin-glass : effect of temperature changes below Tg
The magnetic properties of a spin-glass depend on the time spent in the low-temperature phase: this is the so-called ageing phenomenon. We present measurements of the low-frequency a.c.
