Unitarity of theories containing fractional powers of the d'Alembertian operator [PDF]
, 2014 We examine the unitarity of a class of generalized Maxwell U(1) gauge theories in (2+1) D containing the pseudodifferential operator $\Box^{1-\alpha}$, for $\alpha \in [0,1)$.

Interpolating Quantum Electrodynamics [PDF]
Few-Body Systems, 2018 We discuss the interpolation between the instant form dynamics (IFD) and the light-front dynamics (LFD) proposed by Dirac in 1949 and present its application to quantum electrodynamics (QED). Our analysis clarifies any conceivable confusion in the prevailing notion of the equivalence between the IFD at infinite momentum frame and the LFD. Entwining the

The anomalous electron magnetic moment and Lamb shift in the new approach in quantum electrodynamics [PDF]
arXiv, 2023 In a previous paper by the author a new approach in quantum electrodynamics was proposed in which the electronic and electromagnetic fields are ordinary c-numbers in contradistinction to noncommuting q-numbers used in the standard formulation of quantum electrodynamics.

Integral Formulation of Macroscopic Quantum Electrodynamics in Dispersive Dielectric Objects [PDF]
, 2022 We propose an integral formulation of macroscopic quantum electrodynamics in the Heisenberg picture for linear dispersive dielectric objects of finite size, utilizing the Hopfield-type approach. By expressing the electromagnetic field operators as a function of the polarization density field operator via the retarded Green function for the vacuum, we ...

Large N external-field quantum electrodynamics
Journal of High Energy Physics, 2022 We advocate the study of external-field quantum electrodynamics with N charged particle flavors. Our main focus is on the Heisenberg-Euler effective action for this theory in the large N limit which receives contributions from all loop orders.
