Dynamic Melting and Decoupling of the Vortex Lattice in Layered Superconductors
arXiv:cond-mat/9712271 · doi:10.1103/PhysRevB.57.13800
Abstract
The dynamic phase diagram of vortex lattices driven in disorder is calculated in two and three dimensions. A modified Lindemann criterion for the fluctuations of the distance of neighboring vortices is used, which unifies previous analytic approaches to the equilibrium and non-equilibrium phase transitions. The temperature shifts of the dynamic melting and decoupling transitions are found to scale inversely proportional to large driving currents. A comparison with two-dimensional simulations shows that this phenomenological approach can provide quantitative estimate for the location of these transitions.
