Researchers have found quantitative evidence for a mechanism long predicted to be responsible for high-temperature superconductivity. Led by JC Séamus Davis of the University of Oxford, UK, the team used quantum microscopy to study a high-temperature superconductor called bismuth strontium calcium copper oxide (BSCCO). The work reveals that electrons in this material appear to enter a superfluid state due to strong electron pairing, which then allows them to move without any dissipation.
