Dynamic correlation in vortex liquids and solids

The velocity profile of vortices driven by a non-uniform Lorentz force cont ains 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 t he solid. Application to the glassy states bordering the upper and lower cr itical points is discussed.
