Title: Nonequilibrium Dynamics of Pinned Elastic Lattices: Moving Smectic and Transversely Driven Charge-Density Waves

Abstract: After a brief introduction to the problem, I will describe our recent progress in understanding the dynamics of driven periodic media, as realized for example in vortex lattices, Wigner crystals and charge density waves (CDW). I will then apply this insight to the study of CDW's, driven transversely to the 2k_F ordering direction, and show that nonequilibrium dynamic effects are drammatic, even when the collective CDW state is stationary.
