Fleeting fluctuations in superconductivity disappear close to transition temperature

Sunday, February 13, 2011 - 18:30 in Physics & Chemistry

As part of an ongoing effort to uncover details of how high-temperature superconductors carry electrical current with no resistance, scientists have measured fluctuations in superconductivity that disappear 10-15 Kelvin (K) above the transition temperature. The findings suggest that the transition to the non-superconducting state is driven by a loss of coherence among electron pairs.
