Abstract

High-temperature superconductors such as cuprates exhibit strange behaviors when they are in a metallic state, for example at temperatures above their critical temperature. A new theoretical analysis of the perovskite iridate Sr₂IrO₄, which shares some properties with cuprates, offers insight into the reason for these behaviors.
