Computer simulations of flux pinning and flux flow in two dimensions
Abstract
The deformations of a two-dimensional vortex lattice pinned by a random configuration of pinning centres are studied by a molecular dynamics annealing method. The pinning centres collectively induce a softening of the vortex lattice. The shear modulus decreases with increasing strength of the random potential. At a certain strength Aplas, the pinning centres start to induce plastic deformations in the vortex lattice. The lattice is distorted …
