Superconductivity with Strong and Fragile Flavors

10.09.2019 13:00 – 14:30

Superconductivity is a fascinating phenomenon with tremendous application potential. It also constitutes a research field with seemingly inexhaustible supply of new discoveries. In 2019, the recorded for highest transition temperature was lifted close to room temperature [1]. Even more recently, superconductivity was synthesized in a thin film nickelate oxide compound [2] for the first time. In this seminar, we will return to the long-standing problem of cuprate superconductivity. Recent results discussing the ingredients for cuprate superconductivity will be presented [3]. Finally, new unpublished results on how high-temperature superconductivity and charge ordering co-exist will be put forward. It will be shown how different charge density wave ordering tendencies can dissect superconductivity into strong and fragile flavors [4].
