The quantum electrodynamics for dyons
D. O. R. Azevedo, O. M. Del Cima, T. S. Dias +1
The quantum electrodynamics for massive fermions carrying electric and magnetic charges, the dyons, is proposed based on the 1960's seminal works by Cabibbo, Ferrari, and Salam, wi…

The spectrum consistency of the three fermion family quantum electrodynamics in three space-time dimensions [Phys. Rev. Lett. 124 (2020) 131601] is analyzed. It h…
Is there any Nambu monopolium out there?
D. O. R. Azevedo, M. L. Bispo, O. M. Del Cima +2
Magnetic monopoles have been a subject of study for more than a century since the first ideas by A. Vaschy and P. Curie, circa 1890. In 1974, Y. Nambu proposed a model for magnetic…
On the stability and spectral properties of the two-dimensional Brown-Ravenhall operator with a short-range potential
M. B. Alves, O. M. Del Cima, D. H. T. Franco
The Brown-Ravenhall operator was initially proposed as an alternative to describe the fermion-fermion interaction via Coulomb potential and subject to relativity. This operator is…
