> You mean like the photon and, iirc, all the other neutrally charged elementary particles? You are missing the point. Photon (and every such other elementary particle that annihilates itself we know) is a boson. Majorana fermion is a fermion whose anti-particle is itself. No such elementary particle exists (so far). What these people have done is a way of arranging some electrons such that they behave like Majorana fermions.
