Signatures of Majorana zero-modes in nanowires, quantum spin
... Majorana zero-modes, also referred to as Majorana bound states or Majorinos, are states in the middle of the excitation gap of a superconductor (so at zero excitation energy), bound to a magnetic vortex or other defect. The name goes back to a concept introduced by the Italian physicist Ettore Major ...
