Completing the Theory of Electron with Gravitational Torsion

We demonstrate that classical and quantum electrodynamics can be completed by gravitational torsion appearing in Einstein-Cartan-Sciama-Kibble theory of gravity, providing the missing part of the electron theory. One of the equations of this theory, a version of Dirac type equation for fermions called Hehl-Datta equation, contains a gravitational spin-torsion term in the Lagrangian density for quantum electrodynamics. This term relates the charged fermion spin to gravitational torsion and provides a mechanical energy counter-balance to the infinite electromagnetic self-energy. As a result, there is no "bare" mass for an electron, nor is renormalization required for many scenarios.

Comment on `Relativistic wave-particle duality for spinors'

In a recent paper [1], it has been proposed that relativistic wave-particle duality can be embodied in a relation that shows that the four-velocity of a particle is proportional to the Dirac four-current. In this note we bring out some problems with that idea. In particular, we point out that, in line with existing literature on Einstein-Cartan gravity with torsion, the spin-torsion term should represent negative energy. Moreover, if what is proposed in Eq. (20) of [1] is correct, then the spin torsion term would be zero in the rest frame of the fermion. We suggest a possible resolution of that dilemma.
