Does the existence of Majorana zero mode in superconducting vortices imply the superconductivity is topologically non-trivial?

Lokman Tsui, Zi-Xiang Li, Yen-Ta Huang +2

We show that the presence of Majorana zero modes (2D), and chiral-dispersing Majorana modes (3D), in the vortex cores of superconductors are neither sufficient nor necessary condit…
