Superconductivity with two-fold symmetry-new evidence for topological superconductor SrxBi2Se3
(PHYSorg.com Physics)

The study of topological superconductors (TSCs) is a hotspot in the field of condensed matter physics, and has drawn great attention in recent years. Now, Prof. Hai-Hu Wen`s group from Nanjing University has succeeded in detecting the two-fold symmetry of superconductivity in SrxBi2Se3, which provides new evidence for the argument that SrxBi2Se3 is a TSC.
