November 20 9h30: Prof. Puig’s invited talk at TADeF 2019 (Faculty of Science, UAB)

The “Anual Meeting of Physic PhD students” (Trobada Anual de Doctorands en Física, TADeF2019) will take place the 20th and 21st of November in the Faculty of Science of the Universitat Autònoma de Barcelona. The main objective of this meeting is to provide a big picture of all the research in Physics at the PhD level that is done in the UAB and surrounding institutes. With this aim, the meeting will consist mainly of short talks (10’+3′) from PhD researchers and three keynote talks from international invited speakers of general interest, as well as a poster session.

Prof. Teresa Puig will be the first invited speaker and will talk about “High Temperature Superconductors: Complex materials with novel physics opportunities ” on Wednesday November 20 at 9h30 at Sala Actes of UAB Faculty of Science.

ABSTRACT:

Superconductivity is a macroscopic quantum phenomenon with outstanding properties and impact in many applications. The quantum nature of superconductivity enables the formation of a condensate at the energy ground state by electron-pairing (Cooper pairs) providing zero resistance materials. Since high temperature superconducting (HTS) materials were discovered 30 years ago, new opportunities were envisaged because large electrical currents without losses could be expected at liquid nitrogen temperatures, however they faced unknown physics and new materials engineering complexities. HTS are strongly correlated systems showing unconventional superconductivity and novel vortex physics appear associated to high thermal fluctuations, larger crystalline anisotropy and nanometric nature of the HTS superconducting parameters. Beyond the still unsolved questions, nowadays, the international community is able to fabricate HTS materials for high current energy efficient applications (high power cables, wind generators, electrical aviation) and large scale infrastructures (fusion, circular colliders, high frequency NMR).

In this presentation, I will introduce the basic principles of superconductivity and discuss the unconventional physics of HTS. I will then present our contributions specially in the area of vortex physics of HTS materials. I will finalize with a brief summary of the present applications of HTS.
