Unraveling The Cuprates: Scientists demonstrate link between key components in High Temperature superconductivity

High temperature superconductors have baffled scientist since their discovery in the 1980s. However, a team led by researchers from Brookhaven National Laboratory (BNL) and Cornell University recently conducted a series of experiments which intimate a strong parental connection between the so called “electron density wave” phase and the “pseudo gap” phase, key components seen as responsible for superconductivity in high temperature superconductors.

Led by Séamus Davis, a physicist at Brookhaven and the J.G. White Distinguished Professor of Physical Sciences at Cornell, the team sought to answer the question: “Which of these electrons provide the components that make up the density wave state in cuprates”, the cuprates being a family of copper-oxygen based superconductors.  They were able to answer this question by identifying relationships between “the energy and momenta of the relevant electrons.” in the two phases.
