El GEFES organiza un simposio sobre Materiales Superconductores en la XXXVII Reunión Bienal de la Real Sociedad Española de Física, que se celebrará en Zaragoza, del 15 al 19 de julio de 2019. Este simposio se celebrará el lunes 15 y el martes 16 de julio.


Abstract: Superconductivity is a property of some materials that do not show electrical resistance below a critical temperature. It is a very active research area that continues to pose new challenges, the most recent being superconductivity in hydrides at extreme pressures and with record temperatures and superconductivity in rotated graphene bilayers. At the fundamental level, much effort is devoted to understanding the mechanisms responsible for superconductivity in high temperature and other nonconventional superconductors, understanding superconductivity at the nanoscale or discovering new superconductors. Superconductivity can be used in a large number of applications (medicine, high energy Physics, fusion, energy generation and storage, sensors, quantum computers,…), many still in development. To date, superconductivity applications that have reached the market use low Tc materials. However, in recent years the technology has reached a high degree of maturity, with advances in the development of superconducting high temperature ribbons and wires that have already allowed the development of many prototypes for the energy sector on a real scale.
The symposium will address the latest advances and challenges of the research on superconducting materials in its different aspects: synthesis, characterization and properties, theory and microscopic foundations, hybrid hetero-structures, material optimization and application development. In addition to presenting the latest developments of this field, the symposium aims to promote collaborations among the Spanish groups that investigate on superconductivity.
The symposium will include an invited talk, oral presentations selected from the abstracts received and poster sessions. In the morning, Laura Greene, chief scientist of the National MagLab in Tallahassee, will give a plenary talk on superconducting materials. The day will also include outreach activities on superconductivity.

Charla plenaria: Laura Green (National Mag Lab, Florida State University)

Laura H Greene is the chief scientist at the National MagLab, Eppes Professor of Physics at Florida State University, and past-president of the American Physical Society. Her research is in quantum materials, including high-temperature superconductivity. Greene’s service includes being a Commission Chair and a vice president of the Council of the International Union of Pure and Applied Physics on the Board of Directors of the American Association for the Advancement of Science, and co-chairs the Decadal Survey for Materials Research for the NAS. Greene is a member of the NAS, and a fellow of the American Academy of Arts and Sciences, the Institute of Physics (UK), the AAAS, and the APS. She has been a Guggenheim Fellow and garnered numerous awards, including the Lawrence Award from the U.S. Department of Energy, and the APS Maria Goeppert-Mayer Award. She has co-authored over 200 publications and presented over 500 invited talks.
