Title Smectic Vortex Glass
Abstract I will discuss a newly proposed phase - "smectic vortex glass" (SmVG), that arises when a magnetic field is applied in a type II superconductor transversely to correlated columnar disorder. SmVG is characterized by an infinitely anisotropic electrical transport, resistive (dissipationless) for current perpendicular to (along) columnar defects. Its positional order is also quite unusual, long-ranged with true Bragg peaks along columnar defects and logarithmically rough vortex lattice distortions with quasi-Bragg peaks transverse to columnar defects. For low temperatures and sufficiently weak columnar-only disorder, SmVG is a true topologically-ordered “Bragg glass”, characterized by a vanishing dislocation density.
