Physicists used electrical noise analysis to investigate the pseudogap phenomenon in cuprate superconductors, a key mystery behind high-temperature superconductivity that has puzzled researchers for nearly 40 years. The study, led by Milan Allan and Ingmar Swart, examined how missing electrons behave above the superconducting transition temperature, potentially shedding light on whether electron pairing precedes or coexists with superconductivity.
Background
Cuprate superconductors discovered in the late 1980s operate at temperatures reachable with liquid nitrogen, making them practically significant, but their underlying mechanism remains one of the biggest unsolved problems in condensed matter physics.
