Experimental Implementations of the Superconductor-Insulator Transition

摘要

Various experimental observations of the superconductor-insulator transition are described and compared with two theoretical models: one based on boson-vortex duality and the other where the superconducting fluctuations at low temperatures in the magnetic field are calculated. The latter shows that the superconducting fluctuations in dirty but homogeneous superconductor act as grains in a granular superconductor.
