Theory of plastic vortex creep
J. Kierfeld, H. Nordborg, V. M. Vinokur
We develop a theory for plastic flux creep in a topologically disordered vortex solid phase in type-II superconductors. We propose a detailed description of the plastic vortex cree…
Dislocations and the critical endpoint of the melting line of vortex line lattices
J. Kierfeld, V. Vinokur
We develop a theory for dislocation-mediated structural transitions in the vortex lattice which allows for a unified description of phase transitions between the three phases, the…
Interacting Arrays of Steps and Lines in Random Media
J. Kierfeld, T. Hwa
The phase diagram of two interacting planar arrays of directed lines in random media is obtained by a renormalization group analysis. The results are discussed in the contexts of t…
Topological Order in the Vortex Glass Phase of High-Temperature Superconductors
J. Kierfeld, T. Nattermann, T. Hwa
The stability of a vortex glass phase with quasi-long-range positional order is examined for a disordered layered superconductor. The role of topological defects is investigated us…
