Dynamic correlation in vortex liquids and solids

The velocity profile of vortices driven by a non-uniform Lorentz force contains information on the dynamic correlation of the moving liquid, lattice, and glassy phases. We describe transport experiments using a disk geometry that allow the velocity profile to be measured and analyzed in terms of the hydrodynamic motion of the liquid, and the plastic and elastic motion of the solid. Application to the glassy states bordering the upper and lower critical points is discussed.
