IPB Colloquium by Philipp Hansmann


You are cordially invited to the IPB COLLOQUIUM which will be held on Tuesday, 15 October 2019 at 12:00 in the “Zvonko Marić” lecture hall of the Institute of Physics Belgrade. The talk entitled

A new era in superconductivity: Dawn of the nickel age?

will be given by Prof. Dr. Philipp Hansmann (Max Planck Institute for Chemical Physics of Solids, Dresden, Germany). Abstract of the talk:

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.
