Theory and Experiments for Disordered Elastic Manifolds, Depinning, Avalanches, and Sandpiles
Kay Joerg Wiese
Domain walls in magnets, vortex lattices in superconductors, contact lines at depinning, and many other systems can be modelled as an elastic system subject to quenched disorder. I…
Universal Force Correlations in an RNA-DNA Unzipping Experiment
Kay Joerg Wiese, Mathilde Bercy, Lena Melkonyan +1
We study unzipping of a complementary RNA-DNA helix applied to an external force, focusing on the force-force correlations. While at the microscopic level these are given by the se…
Depinning transition of charge-density waves: mapping onto symmetric theory with and loop-erased random walks
Kay Joerg Wiese, Andrei A. Fedorenko
Driven periodic elastic systems such as charge-density waves (CDWs) pinned by impurities show a non-trivial, glassy dynamical critical behavior. Their proper theoretical descriptio…
Field Theory of Disordered Elastic Interfaces at 3-Loop Order: The -Function
Kay Joerg Wiese, Christoph Husemann, Pierre Le Doussal
We calculate the effective action for disordered elastic manifolds in the ground state (equilibrium) up to 3-loop order. This yields the renormalization-group -function to third…
Field Theory of Disordered Elastic Interfaces at 3-Loop Order: Critical Exponents and Scaling Functions
Christoph Husemann, Kay Joerg Wiese
For disordered elastic manifolds in the ground state (equilibrium) we obtain the critical exponents for the roughness and the correction-to-scaling up to 3-loop order, i.e. third o…
Equilibrium avalanches in spin glasses
Pierre Le Doussal, Markus Mueller, Kay Joerg Wiese
We study the distribution of equilibrium avalanches (shocks) in Ising spin glasses which occur at zero temperature upon small changes in the magnetic field. For the infinite-range…
Avalanche-size distribution at the depinning transition: A numerical test of the theory
Alberto Rosso, Pierre Le Doussal, Kay Joerg Wiese
We calculate numerically the sizes S of jumps (avalanches) between successively pinned configurations of an elastic line (d=1) or interface (d=2), pulled by a spring of (small) str…
How to measure the effective action for disordered systems
Kay Joerg Wiese, Pierre Le Doussal
In contrast to standard critical phenomena, disordered systems need to be treated via the Functional Renormalization Group. The latter leads to a coarse grained disorder landscape,…
Cusps and shocks in the renormalized potential of glassy random manifolds: How Functional Renormalization Group and Replica Symmetry Breaking fit together
Pierre Le Doussal, Markus Mueller, Kay Joerg Wiese
We compute the Functional Renormalization Group (FRG) disorder- correlator function R(v) for d-dimensional elastic manifolds pinned by a random potential in the limit of infinite e…
Functional Renormalization for Disordered Systems, Basic Recipes and Gourmet Dishes
Kay Joerg Wiese, Pierre Le Doussal
We give a pedagogical introduction into the functional renormalization group treatment of disordered systems. After a review of its phenomenology, we show why in the context of dis…
Numerical Calculation of the Functional renormalization group fixed-point functions at the depinning transition
Alberto Rosso, Pierre Le Doussal, Kay Joerg Wiese
We compute numerically the sequence of successive pinned configurations of an elastic line pulled quasi-statically by a spring in a random bond (RB) and random field (RF) potential…
Supersymmetry Breaking in Disordered Systems and Relation to Functional Renormalization and Replica-Symmetry Breaking
Kay Joerg Wiese
In this article, we study an elastic manifold in quenched disorder in the limit of zero temperature. Naively it is equivalent to a free theory with elasticity in Fourier-space prop…
Derivation of the Functional Renormalization Group Beta-Function at order 1/N for Manifolds Pinned by Disorder
Pierre Le Doussal, Kay Joerg Wiese
In an earlier publication, we have introduced a method to obtain, at large N, the effective action for d-dimensional manifolds in a N-dimensional disordered environment. This allow…
