Take the 2-minute tour ×  My knowledge of quantum mechanics is
rather limited, but what I always understood was that Bosons
have integer spins and Fermions have half-integer spins.  My
question is very simple: the Majorana particle has no spin
according to this paper and this Physics Today article which
(without wanting to go into a philosophical mathematical
discussion) I would call integer spin. That would make the
particle a Boson. So what is the reason that the particle is
classified as a Fermion?  share|improve this question Do you
have a source for the statement that Majorana particles have no
spin? –  Chris White Feb 19 '13 at 6:35 Here:

the last post has a sentence saying: "As quasiparticles go, the
Majorana is incredibly featureless: It’s chargeless, spinless,
massless, and without energy" –  Michiel Feb 19 '13 at 6:51
Michael, you're actually wrong. Majorana fermions are defined as
fermions that are comp
