A new era in superconductivity: Dawn of the nickel age?
одржаће Проф. др Филип Хансман (Max Planck Institute for Chemical Physics of Solids, Dresden, Germany)
The idea to find cuprate-analogue high-Tc superconductors is as old as the cuprate high-Tc phenomenon itself. This materials hunt has been revitalized in the past decade due to technological advances in heterostructure synthesis. Especially nickelates have always been high on the candidates list and are in a continuous focus of experimental and theoretical researchers alike. In August this year, finally, superconductivity was observed for the first time in a nickelate structure when Sr-doped NdNiO2 was found to be superconducting at 10 K. In this colloquium talk we will give a „theory-biased“ overview about past and present efforts put into nickelate-based superstructures, as well as preliminary insights about the new superconductors from a low energy effective model perspective.
