Abstract
We study a three-dimensional model of driven vortices in weakly coupled layered superconductors with strong pinning. Above the critical force Fc, we find a plastic flow regime in which pancakes in different layers are uncoupled, corresponding to a pancake gas. At a higher F, there is a “smectic flow” regime with short-range interlayer order, corresponding to an entangled line liquid. Later, the transverse displacements freeze and vortices become correlated along the c axis, resulting in a transverse solid. Finally, at a force Fs the longitudinal displacements freeze and we find a coherent solid of rigid lines.
