Depinning and flow of a vortex line in an uniaxial random medium
Federico Elías, Kay Jörg Wiese, Alejandro B. Kolton
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 supe…
Force Correlations in Disordered Magnets
Cathelijne ter Burg, Felipe Bohn, Gianfranco Durin +2
We present a proof of principle for the validity of the functional renormalization group, by measuring the force correlations in Barkhausen-noise experiments. Our samples are soft…
The Spatial Shape of Avalanches
Zhaoxuan Zhu, Kay Joerg Wiese
In disordered elastic systems, driven by displacing a parabolic confining potential adiabatically slowly, all advance of the system is in bursts, termed avalanches. Avalanches have…
Field theory conjecture for loop-erased random walks
Andrei A. Fedorenko, Pierre Le Doussal, Kay Joerg Wiese
We give evidence that the functional renormalization group (FRG), developed to study disordered systems, may provide a field theoretic description for the loop-erased random walk (…
Depinning in a two-layer model of plastic flow
Pierre Le Doussal, M. Cristina Marchetti, Kay Joerg Wiese
We study a model of two layers, each consisting of a d-dimensional elastic object driven over a random substrate, and mutually interacting through a viscous coupling. For this mode…
How to measure Functional RG fixed-point functions for dynamics and at depinning
Pierre Le Doussal, Kay Joerg Wiese
We show how the renormalized force correlator Delta(u), the function computed in the functional RG (FRG) field theory, can be measured directly in numerics and experiments on the d…
