Galitski, Victor M and Refael, G and Fisher, Matthew PA and Senthil, T (2005) Vortices and Quasiparticles near the Superconductor-Insulator Transition in Thin Films. In: Physical Review Letters, 95 (7).
We study the low temperature behavior of an amorphous superconducting film driven normal by a perpendicular magnetic-field (B). For this purpose we introduce a new two-fluid formulation consisting of fermionized field-induced vortices and electrically neutralized Bogoliubov quasiparticles (spinons) interacting via a long-ranged statistical interaction. This approach allows us to access a novel non-Fermi-liquid phase, which naturally interpolates between the low B superconductor and the high B normal metal. We discuss the properties of the resulting "vortex metal" phase.
