Interface depinning in random media: a physicist's approach
- Thomas Nattermann (Universität zu Köln, Germany)
Abstract
In this talk I introduce and 'solve' a minimal model for the depinning of a driven interface in random media. It is shown by qualitative methods and a functional renormalization group calculation that the interface close to the depinning threshold is self affine and characterized by a number of critical exponents which obey scaling relations.
The extension of these consideration to interfaces driven by an oscillating force is briefly discussed.
