Finster and Kamran propose causal fermion systems and Riemannian fermion systems as a framework describing non-smooth geometries, in particular, providing a setting for spinors on singular spaces.
He published his research on the "Extended Dirac Equation for Elementary Fermions based on Applying 8-Dimensional Spinors." DOI: 10.13140/RG.2.2.23994.90569
But we do have the next best thing -- electrons working together in such a way that their collective behaviour produces something just like a Majorana fermion.

The single-particle and collective excitations of the system under consideration manifest themselves as poles of the single-particle and two-particle Green's functions, but the corresponding expressions for the Green's functions cannot be evaluated exactly because the interaction part of the Hubbard Hamiltonian is quartic in the fermion fields.
which is the Hamilton-Jacobi equation satisfied by a fermion particle of mass m moving in the black hole with the electromagnetic potential [A.sub.[mu]].
where [F.sub.s] is the fermion number operator and [[delta].sub.S] = [+ or -]1 is the space-time spin statistics index.
The monotonic decreasing behavior of the chemical potential with temperature for d/s [greater than or equal to] 1 is understood from the argument based on the fact that the internal energy U diminishes from its zero temperature value [E.sub.F] after adiabatically adding a fermion at the small temperatures T [much less than] [T.sub.F].
The newly discovered particle, known as a Weyl fermion, resembles a massless electron that darts around and through the material in unusual and exciting ways, physicists report online July 16 in Science.
Two new particles long thought to have existed -- the pentaquark and the Weyl fermion, were experimentally confirmed in groundbreaking news out of MIT, Princeton, and the Large Hadron Collider (LHC).
The researchers analyzed the data gathered at the LHC between 2011 and 2012, combining the Higgs decays into bottom quarks and tau leptons, both of which belong to the fermion particle group and the results revealed that an accumulation of these decays comes about at a Higgs particle mass near 125 gigaelectron volts (GeV) and with a significance of 3.8 sigma.
The final body chapter explores applications and analogies in other areas of science, including finite fermion systems, astrophysical nucleation, atmospheric aerosol condensation, and medical imaging and therapy.
The physical mass is deduced by locating the pole of the fermion propagator (i([??] + m)/([p.sup.2] - [m.sup.2] + i[epsilon])) in thermal background.
At that time a known particle with zero mass was only the Photon, a Boson, with tsh spin but he reduced mass of a fermion or an electron in Dirac's equation and got a pair of particles with zero mass and therefore with no electric charge because if a particle has no rest mass but spin half of tsh then we are forced to assign it, zero electric charge.
