Quasi-static crack propagation in heterogeneous media
Sharad Ramanathan, Deniz Ertaş, Daniel S. Fisher
The dynamics of a single crack moving through a heterogeneous medium is studied in the quasi-static approximation. Equations of motion for the crack front are formulated and the re…
Stability of Elastic Glass Phases in Random Field XY Magnets and Vortex Lattices in Type II Superconductors
Daniel S. Fisher
A description of a dislocation-free elastic glass phase in terms of domain walls is developed and used as the basis of a renormalization group analysis of the energetics of disloca…
Dynamic Critical Phenomena in Channel Flow
Joe Watson, Daniel S. Fisher
A simple model of the driven motion of interacting particles in a two dimensional random medium is analyzed, focusing on the critical behavior near to the threshold that separates…
Two-Channel Kondo Physics from Tunnelling Impurities with Triangular Symmetry
Aris L. Moustakas, Daniel S. Fisher
Tunnelling impurities in metals have been known for some time to have the potential for exhibiting Kondo-like physics. However previous models based on an impurity hopping between…
