Driven Dynamics of Superconducting Vortices
Physics Division Colloquium - 22 Sept. 2000

Vortices in superconductors form an ensemble of interacting lines that display complex phase diagrams containing solid, liquid, and glassy states, and rich dynamic behavior including hydrodynamic, elastic and plastic motion. A brief introduction to the equilibrium phase diagram of vortex matter will be followed by a description of the driven motion revealed by novel "controlled gradient" transport experiments.
