Nonsteady relaxation and critical exponents at the depinning transition

  author={Ezequiel Ferrero and Sebastian Bustingorry and Alejandro B. Kolton},
  journal={Physical Review E},
We study the nonsteady relaxation of a driven one-dimensional elastic interface at the depinning transition by extensive numerical simulations concurrently implemented on graphics processing units. We compute the time-dependent velocity and roughness as the interface relaxes from a flat initial configuration at the thermodynamic random-manifold critical force. Above a first, nonuniversal microscopic time regime, we find a nontrivial long crossover towards the nonsteady macroscopic critical… 

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

Numerical simulations of critical dynamics in anisotropic magnetic films with the stochastic Landau-Lifshitz-Gilbert equation.

The results show that the dynamic universality class of the sLLG equation is different from those of the Monte Carlo dynamics and quenched Edwards-Wilkinson equation, and it may lead to alternative understanding of experiments.

Depinning in the quenched Kardar-Parisi-Zhang class I: Mappings, simulations and algorithm

This work develops scaling arguments for all critical exponents, including size and duration of avalanches, and presents a new algorithm to numerically estimate the effective ($m$-dependent) elasticity $c$, and the effective KPZ non-linearity $\lambda$.

Distribution of velocities in an avalanche, and related quantities: Theory and numerical verification

We study several probability distributions relevant to the avalanche dynamics of elastic interfaces driven on a random substrate: The distribution of size, duration, lateral extension or area, as

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 =∞.

Oslo model, hyperuniformity, and the quenched Edwards-Wilkinson model.

Simulations of the one-dimensional Oslo rice pile model in which the critical height at each site is randomly reset after each toppling are presented, finding that all critical exponents have values consistent with simple rationals.

Viscoelastic Interfaces Driven in Disordered Media and Applications to Friction

Many complex systems respond to a continuous input of energy by an accumulation of stress over time, interrupted by sudden energy releases called avalanches. Recently, it has been pointed out that

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

Spin-reorientation critical dynamics in the two-dimensional XY model with a domain wall.

This paper investigates spin-reorientation critical dynamics in the two-dimensional XY model with Monte Carlo simulations and theoretical analyses based on the Langevin equation at the Kosterlitz-Thouless phase transition, and deduced the relation ψ=η/2z is analytically deduced in the long-wavelength approximation.

Universality in Self-Organized Criticality

This thesis tries to cover some general aspects of SOC from the perspective of phase transitions and their associated universal features, and this is what the reader should expect from the book.

Random number generators for massively parallel simulations on GPU

A broad review of existing CUDA variants of random-number generators is provided and the CUDA implementation of a new massively parallel high-quality, high-performance generator with a small memory load overhead is presented.
