Electrons by themselves are fermions, particles that obey the Pauli exclusion principle, which means each electron tends to keep its own quantum state. Cooper pairs, however, act like bosons ...

"The electron pairs are telling us that they are ready to be superconducting, but something is stopping them," said Ke-Jun Xu, a Stanford graduate student in applied physics and paper co-author.

Scientists seeking to explain high-temperature superconductivity have been violating the Pauli exclusion principle, a team of researchers from the University of Illinois at Urbana-Champaign and ...

PROVIDENCE, R.I. [Brown University] -- For years, physicists have assumed that Cooper pairs, the electron duos that enable superconductors to conduct electricity without resistance, were two-trick ...

Confirming a prediction made in 1969, the electron pairs were spotted in strontium titanate using a single-electron transistor. The observation could provide useful insights into the nature of ...

Unlike low-temperature superconductors, which are metals, high-temperature superconductors are insulators in their normal state. Even more puzzling, half of the electron states are empty.
