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. Its field theory possesses a well-controlled perturbative expansion around its upper critical dimension. Contrary to standard field theory, the renormalization group flow involves a function, the disorder correlator $\Delta(w)$, therefore termed the functional renormalization group (FRG). $\Delta(w)$ is a physical… Expand
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. Expand
Force-Force Correlations in Disordered Magnets
We study experimentally the force-force correlator in Barkhausen experiments. We observe two distinct universality classes, depending on the range of spin interactions. For short-ranged elasticity,Expand
Damage spreading in quasi-brittle disordered solids: II. What the statistics of precursors teach us about compressive failure
We investigate numerically and theoretically the precursory intermittent activity characterizing the preliminary phase of damage accumulation prior to failure of quasi-brittle solids. We use aExpand

Thermally activated intermittent dynamics of creeping crack fronts along disordered interfaces
It is shown that the proposed model also quantitatively accounts for the complex self-affine scaling morphology of crack fronts and their temporal evolution, for the spatial and temporal correlations of the local velocity fields and for the avalanches size distribution of the intermittent growth dynamics.
