Fertile ground for the elusive Majorana 'angel' particle
A new, multi-node FLEET review investigates the search for Majorana fermions in iron-based superconductors. The elusive Majorana fermion, or 'angel particle' proposed by Ettore Majorana in 1937, simultaneously behaves like a particle and an antiparticle - and surprisingly remains stable rather than being self-destructive. Majorana fermions promise information and communications technology
