We study numerically the depinning transition of driven elastic interfaces in a random-periodic medium with localized periodic-correlation peaks in the direction of motion. The analysis of the moving interface geometry reveals the existence of several characteristic lengths separating different length-scale regimes of roughness. We determine the scaling behavior of these lengths as a function of the velocity, temperature, driving force, and transverse periodicity. A dynamical roughness diagram…

Anisotropic finite-size scaling of an elastic string at the depinning threshold in a random-periodic medium

We numerically study the geometry of a driven elastic string at its sample-dependent depinning threshold in random-periodic media. We find that the anisotropic finite-size scaling of the average

The elastic depinning transition of vortex lattices in two dimensions

Large-scale numerical simulations are used to study the elastic dynamics of two-dimensional vortex lattices driven on a disordered medium in the case of weak disorder. We investigate the so-called

Uniqueness of the thermodynamic limit for driven disordered elastic interfaces

We study the finite-size fluctuations at the depinning transition for a one-dimensional elastic interface of size L displacing in a disordered medium of transverse size M = kLζ with periodic boundary

Maximum relative height of elastic interfaces in random media.

The distribution of the maximal relative height of self-affine one-dimensional elastic interfaces in a random potential is studied and Pickands' theorem is derived to derive an exact analytical description for the right tail of the MRH distributions.

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

Roughening of the anharmonic Larkin model.

The roughening of d-dimensional directed elastic interfaces subject to quenched random forces is studied, and it is shown that such d=1 case is directly related to a family of Brownian functionals parameterized by n, ranging from the random-acceleration model for n=1 to the Lévy arcsine-law problem for n =∞.

Length scales and scale-free dynamics of dislocations in dense solid solutions

The fundamental interactions between an edge dislocation and a random solid solution are studied by analyzing dislocation line roughness profiles obtained from molecular dynamics simulations of

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

Mean-field theories for depinning and their experimental signatures.

This work model forces as an Ornstein-Uhlenbeck process, and solves the model largely analytically, allowing it to describe in all regimes the distributions of velocity, avalanche size, and duration.

A numerical study of the statistics of roughness parameters for fluctuating interfaces

This work considers three cases of numerically simulated one-dimensional interfaces and shows that sample-to-sample fluctuations are rather large when measuring the roughness exponent, and suggests a minimum of independent interface realizations should be used to guarantee sufficient statistical averaging.

Electronic Glasses

For more than 50 years our understanding of interacting electronic systems has been essentially based on the Fermi liquid theory. In this way of viewing electrons, the electron is essentially
