Does anybody know anything about non--plane-wave interacting-solutions of Dirac equation?

In QFT, computations are done with plane-wave free solutions of the Dirac equations: if one were to consider full solutions of the Dirac equation in interaction with its own electrodynamic field,...

Is there an a priori way to justify the normalization for which the scalar square of spinors is equal to twice the mass of the spinor field itself?

In QFT we calculate quantities that ultimately depend on the way we normalize spinors; but because in perturbation theories spinor propagators are free then their normalization can be chosen...

Weak-gravity Einstein equations with positive cosmological constant give a graviton with imaginary mass: could this be an argument against gravitons?

If we consider the weak-gravity approximation of the vacuum Einstein field equations with a positive cosmological constant then the field equations for the graviton acquire an imaginary mass term:...

Covariant Inertial Forces for Spinors

Although it is not possible to have a covariant treatment of inertial forces in general, spinor fields we can define specific objects that describe forces of inertial type but which are real...
