Fysikkollokvium

​Välkommen till årets första kollokvium med Annica Black-Schaffer​, Uppsala universitet.

Titel: Topological superconductors and Majorana fermions

​Sammanfattning: 

Topological superconductors with Majorana fermion quasiparticles form a newly discovered class of matter. The Majorana fermion can be seen as half an electron, or more accurately, the electron wave function has split up into two completely separate parts. I will explain the basic physics behind topological superconductors and why Majorana fermions appear, briefly review the current experimental status, and report a few of our recent findings.
