“…There is experimental evidence not only for dynamic melting, but also the structure of the moving lattice and moving smectic have been characterized. The transition was detected by resistive measurements (Bhattacharya andHiggins 1993, Hellerqvist et al 1996) and the structure of the dynamic phases was observed by dynamic decoration techniques (Marchevsky et al 1997, Pardo et al 1998, Troyanovskii et al 1999. Numerical evidence for dynamic melting was found in d = 2 (Koshelev and Vinokur 1994, Ryu et al 1996a, Faleski et al 1996 and also d = 3 (Domínguez et al 1997).…”

A review is given on the theory of vortex-glass phases in impure type-II superconductors in an external field. We begin with a brief discussion of the effects of thermal fluctuations on the spontaneously broken U(1) and translation symmetries, on the global phase diagram and on the critical behaviour. Introducing disorder we restrict ourselves to the experimentally most relevant case of weak uncorrelated randomness which is known to destroy the long-ranged translational order of the Abrikosov lattice in three dimensions. Elucidating possible residual glassy ordered phases, we distinguish betwee positional and phase-coherent vortex glasses. The discussion of elastic vortex glasses, in two and three dimensions occupy the main part of our review. In particular, in three dimensions there exists an elastic vortex-glass phase which still shows quasi-long-range translational order: the `Bragg glass'. It is shown that this phase is stable with respect to the formation of dislocations for intermediate fields. Preliminary results suggest that the Bragg-glass phase may not show phase-coherent vortex-glass order. The latter is expected to occur in systems with weak disorder only in higher dimensions. We further demonstrate that the linear resistivity vanishes in the vortex-glass phase. The vortex-glass transition is studied in detail for a superconducting film in a parallel field. Finally, we review some recent developments concerning driven vortex-line lattices moving in a random environment.Comment: 133 pages Latex with figures. accepted for publication in Adv. Phy
