Size distributions of shocks and static avalanches from the Functional Renormalization Group
Pierre Le Doussal, Kay Jörg Wiese
Interfaces pinned by quenched disorder are often used to model jerky self-organized critical motion. We study static avalanches, or shocks, defined here as jumps between distinct g…
Fluctuation force exerted by a planar self-avoiding polymer
Pierre Le Doussal, Kay Jörg Wiese
Using results from Schramm Loewner evolution (SLE), we give the expression of the fluctuation-induced force exerted by a polymer on a small impenetrable disk, in various 2-dimensio…
Critical interfaces in the random-bond Potts model
Jesper L. Jacobsen, Pierre Le Doussal, Marco Picco +2
We study geometrical properties of interfaces in the random-temperature q-states Potts model as an example of a conformal field theory weakly perturbed by quenched disorder. Using…
Driven particle in a random landscape: disorder correlator, avalanche distribution and extreme value statistics of records
Pierre Le Doussal, Kay Joerg Wiese
We review how the renormalized force correlator Delta(u), the function computed in the functional RG field theory, can be measured directly in numerics and experiments on the dynam…
Statistics of static avalanches in a random pinning landscape
Pierre Le Doussal, A. Alan Middleton, Kay Joerg Wiese
We study the minimum-energy configuration of a d-dimensional elastic interface in a random potential tied to a harmonic spring. As a function of the spring position, the center of…
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 (…
