In the frame of the general Gel’fand – Yaglom formalism, the Fradkin theory for a spin 3/2 particle in presence of external fields is investigated. Applying the standard requirements of relativistic invariance, P-symmetry, existence of a Lagrangi

We consider the quantum theory of the Lorentzian fermionic differential forms and the corresponding bi-spinor quantum fields, which are the expansion coefficients of the forms in the bi-spinor basis of Becher and Joos [7]. The canonical quantization

In the article, using the Gelfand–Yaglom general approach, a new 20-component wave equation for spin 1/2 fermion that is characterized by three mass parameters is derived. Based on the 20-component wave function three auxiliary bispinors are determ

Massive Dirac particles are a superposition of left and right chiral components. Since chirality is not a conserved quantity, the free Dirac Hamiltonian evolution induces chiral quantum oscillations, a phenomenon related to the \textit{Zitterbewegung

A possibility to construct a theory for an electron on the basis of the Dirac equation, where the electromagnetic field potentials are defined as those created by the electron itself, has been analyzed. It is shown that the energy conservation law is

The Hadamard renormalization procedure is applied to a free, massive Dirac field $\ensuremath{\psi}$ on a two-dimensional Lorentzian spacetime. This yields the state-independent divergent terms in the Hadamard bispinor ${G}^{(1)}(x,{x}^{\ensuremath{'
