Driven vortices in confined geometry: the Corbino disk

The fabrication of artificial pinning structures allows a new generation of experiments which can probe the properties of vortex arrays by forcing the m to flow in confined geometries. We discuss the theoretical analysis of su ch experiments in both flux liquids and flux solids, focusing on the Corbin o disk geometry. In the liquid, these experiments can probe the critical be havior near a continuous liquid-glass transition. In the solid, they probe directly the onset of plasticity.
