Interface depinning in a disordered medium - numerical results
We propose a lattice model to study the dynamics of a driven interface in a medium with random pinning forces. The critical exponents characterizing the depinning transition are determined numerically in 1+1 and 2+1 dimensions. Our findings are compared with recent numerical and analytical results for a Langevin equation with quenched noise, which is expected to be in the same universality class.
متن کاملDriven Interface Depinning in a Disordered Medium
The dynamics of a driven interface in a medium with random pinning forces is analyzed. The interface undergoes a depinning transition where the order parameter is the interface velocity v, which increases as v ∼ (F − Fc) for driving forces F close to its threshold value Fc. We consider a Langevin-type equation which is expected to be valid close to the depinning transition of an interface in a ...
متن کاملDepinning of a Polymer in a Multi-interface Medium
In this paper we consider a model which describes a polymer chain interacting with an infinity of equi-spaced linear interfaces. The distance between two consecutive interfaces is denoted by T = TN and is allowed to grow with the size N of the polymer. When the polymer receives a positive reward for touching the interfaces, its asymptotic behavior has been derived in [3], showing that a transit...
متن کاملDepinning in a Random Medium
We develop a renormalized continuum field theory for a directed polymer interacting with a random medium and a single extended defect. The renormalization group is based on the operator algebra of the pinning potential; it has novel features due to the breakdown of hyperscaling in a random system. There is a second-order transition between a localized and a delocalized phase of the polymer; we ...
متن کاملDepinning of a metastable disordered vortex lattice.
We report on experiments investigating the depinning dynamics of a strongly pinned vortex lattice in 2H-NbSe2. We find that the depinning process starts at currents that are well below the critical current of the entire lattice and that it is governed by the formation of contiguous channels of mobile vortices connecting the sample edges. We obtain the formation time of the first channel by moni...
