Latest Pseudogap Stories
Findings published in the journal Science may help researchers synthesize materials that can superconduct at room temperature. College Park, Md.
Scientists seeking to understand the intricacies of high-temperature superconductivity—the ability of certain materials to carry electrical current with no energy loss—have been particularly puzzled by a mysterious phase that emerges as charge carriers are added that appears to compete with superconductivity.
Understanding superconductivity – whereby certain materials can conduct electricity without any loss of energy – has proved to be one of the most persistent problems in modern physics.
A German-French research team has constructed a new model that explains how the so-called pseudogap state forms in high-temperature superconductors.
Japanese and U.S. physicists are offering new details this week in the journal Nature regarding intriguing similarities between the quirky electronic properties of a new iron-based high-temperature superconductor (HTS) and its copper-based cousins.
Scientists have found the strongest evidence yet that a puzzling gap in the electronic structures of some high-temperature superconductors could indicate a new phase of matter.
In a major step toward understanding the mysterious "pseudogap" state in high-temperature cuprate superconductors, a team of Cornell, Binghamton University and Brookhaven National Laboratory scientists have found a "broken symmetry," where electrons act like molecules in a liquid crystal: Electrons between copper and oxygen atoms arrange themselves differently "north-south" than "east-west."
Binghamton University physicist Michael Lawler and his colleagues have made a breakthrough that could lead to advances in superconductors.
Scientists have been trying for some 20 years to understand why the low temperature at which copper-oxide superconductors carry current with no resistance can't be increased to be closer to room temperature.
Scientists at JILA, working with Italian theorists, have discovered another notable similarity between ultracold atomic gases and high-temperature superconductors, suggesting there may be a relatively simple shared explanation for equivalent behaviors of the two very different systems.
