We perform a high-precision calculation of the critical exponents for the long-range elastic string driven through quenched disorder at the depinning transition, at zero temperature. Large-scale simulations avoid finite-size effects and improve accuracy. We explicitly demonstrate the equivalence of fixed-velocity and fixed-driving-force simulations. The roughness, growth, and velocity exponents are calculated independently, and the dynamic and correlation length exponents are derived. The…

The effect of disorder geometry on the critical force in disordered elastic systems

We address the effect of disorder geometry on the critical force in disordered elastic systems. We focus on the model system of a long-range elastic line driven in a random landscape. In the

Roughness and multiscaling of planar crack fronts

We consider numerically the roughness of a planar crack front within the long-range elastic string model, with a tunable disorder correlation length ξ. The problem is shown to have two important

Depinning Transition of a Domain Wall in Ferromagnetic Films

First principle numerical study of domain wall (DW) depinning in two-dimensional magnetic film, which is modeled by 2D random-field Ising system with the dipole-dipole interaction, finds that tuning the strength of the dipoles-d Dipole interaction switches DW dynamics between two different universality classes, corresponding to two distinct dynamic regimes.

Domain walls in magnets, vortex lattices in superconductors, contact lines at depinning, and many other systems can be modeled as an elastic system subject to quenched disorder. The ensuing field

Avalanches and deformation in glasses and disordered systems

In this chapter, we discuss avalanches in glasses and disordered systems, and the macroscopic dynamical behavior that they mediate. We briefly review three classes of systems where avalanches are

Depinning and flow of a vortex line in a uniaxial random medium

We study numerically and analytically the dynamics of a single directed elastic string driven through a 3-dimensional disordered medium. In the quasistatic limit the string is super-rough in the

Universal Scaling of the Velocity Field in Crack Front Propagation.

It is shown that the correlation functions of the velocity field along the front allow us to extract the critical exponents of the transition and to identify the universality class of the system.

Evolution of the average avalanche shape with the universality class

Here it is shown how the average avalanche shape evolves with the universality class of the avalanche dynamics by employing a combination of scaling theory, extensive numerical simulations and data from crack propagation experiments.

Anisotropic avalanches and critical depinning of three-dimensional magnetic domain walls.

The total interface roughness is consistent with self-affine scaling with a roughness exponent ζ≈χ that is much larger than values found previously for the RFIM and related models that explicitly break orientational symmetry by requiring the interface to be single-valued.

Atomic-scale avalanche along a dislocation in a random alloy

The propagation of dislocations in random crystals is evidenced to be governed by atomic-scale avalanches whose the extension in space and the time intermittency characterizingly diverge at the

Notably, the velocity correlation function is nonuniversal at short distances, and obeys the scaling relation nu = 1/(2 - zeta), and agrees with nu(FS), the finite-size-scaling exponent of fluctuations in the critical force.

Large-scale numerical simulations of ultrametric long-range depinning.

A very precise determination of critical exponents is obtained, shown to be indistinguishable from their Euclidean metric counterparts, which opens the way to an analytic real-space renormalization-group approach.

This paper compute to high precision the roughness exponent zeta of a long-range elastic string, at the depinning threshold, in a random medium, using the analytic structure of the problem ("no-passing" theorem), but avoids direct simulation of the evolution equations.

From individual to collective pinning: Effect of long-range elastic interactions

We study the effect of long-range elastic interactions in the dynamical behavior of an elastic chain driven quasistatically in a quenched random pinning potential. This is a generic situation

Threshold critical dynamics of driven interfaces in random media.

The dynamics of driven interfaces in random media are analyzed, focusing on the critical behavior near the depinning threshold. The roughening exponent in the critical region is shown to be

Driven interface depinning in a disordered medium

The dynamics of a driven interface in a medium with random pinning forces is analyzed. The interface undergoes a depinning transition where the order parameter is the interface velocity v, which

A characteristic distortion length of the contact line depinning from a strong defect is predicted to initially increase faster than linearly in time, resulting in unusual dynamical properties.

Two-loop functional renormalization group theory of the depinning transition

We construct the field theory of quasistatic isotropic depinning for interfaces and elastic periodic systems at zero temperature, taking properly into account the nonanalytic form of the dynamical

Renormalization of pinned elastic systems: how does it work beyond one loop?

The field theories for pinned elastic systems at equilibrium and at depinning are studied and it is proved that two-loop renormalizability is proved and that random field attracts shorter range disorder.

Dynamics of Interface Depinning in a Disordered Medium

The motion of an interface in a disordered medium driven by a constant force is one of the paradigms of condensed matter physics. Well known examples are domain walls in random magnets1 and
