Scientists see energy gap modulations in a cuprate superconductor

Scientists studying high-Tc superconductors have definitive evidence for the existence of a state of matter known as a pair density wave -- first predicted by theorists some 50 years ago. Their results show that this phase coexists with superconductivity in a well-known bismuth-based copper-oxide superconductor.
