GHN-colloquium with Prof. Annica Black-Schaffer

Date & Facts

26 Jan 2021
03:30 pm – 05:30 pm

3:30 - 4:40 pm (CET)     Scientific talk & questions (open to EVERYBODY)

4:45 - 5:30 pm (CET)     Networking event (open to members of the GHN)



The GHN-Colloquium talk series features the female scientists of the Grete-Hermann-Network (GHN) – a newly founded international network of female researchers in condensed matter physics and neighboring research areas. Distinguished female researchers are invited to give a lecture on their research and current projects, as well as about their career paths, to inspire young female scientists in particular, and to exchange ideas. After the official talk there will be an internal GHN-networking event.


On 26 January 2021, we are happy to welcome Prof. Annica Black-Schaffer from Uppsala University, who will give a scientific online talk about New Mechanisms and Materials for Odd-Frequency Superconductivity.



Talk abstract


Odd-frequency superconductivity is a very unique superconducting state that is odd in time or, equivalently, frequency, which is opposite to the ordinary behavior of superconductivity. It has been realized to be the key to understand the surprising physics of superconductor-ferromagnet (SF) structures and has also enabled the emerging field of superconducting spintronics. More recent discoveries have also identified odd-frequency superconductivity in a range of known superconductors, such as doped topological insulators and multiband superconductors, such as Sr2RuO4 and UPt3, and also in superconducting heterostructures of Weyl semimetals. In this talk I will give a conceptual introduction to odd-frequency superconductivity followed by a review of a few systems and materials where odd-frequency superconductivity is important for our understanding of the superconducting state.



About Annica Black-Schaffer



Annica Black-Schaffer is a Full Professor in Quantum Matter Theory, Dept. of Physics and Astronomy, a Wallenberg Academy Fellow, and an ERC Starting Grant holder. She received her Ph.D. in condensed matter theory in 2009 from Stanford University and spent 1.5 years as a postdoctoral fellow at the Nordic Institute for Theoretical Physics, NORDITA, in Stockholm. Her research interests span superconductivity, topological states of matter, and strongly correlated electron systems. Her research group is currently mainly focused on the mechanisms and properties of unconventional and topological superconductors with Majorana fermions.
