Abstract:The superconductor-insulator transition (SIT) in thin-film disordered superconductors is a hallmark example of a quantum phase transition. Despite being observed more than 30 years ago, its nature is still under a vivid debate. One intriguing observations concerns the insulating side of the transition, which exhibits some unusual properties. Among them is its current-voltage relation (I − V curve), which includes (1) a conductance that changes abruptly by several orders of magnitude with increasing voltage, (2… Show more
