Electron-positron pairs in physics and astrophysics: from heavy nuclei to black holes
Abstract Due to the interaction of physics and astrophysics we are witnessing in these years a splendid synthesis of theoretical, experimental and observational results originating from threeExpand

Hierarchy spectrum of SM fermions: from top quark to electron neutrino
A bstractIn the SM gauge symmetries and fermion content of neutrinos, charged leptons and quarks, we study the effective four-fermion operators of Einstein-Cartan type and their contributions to theExpand

Semiclassical pair production rate for rotating electric fields
We semiclassically investigate Schwinger pair production for pulsed rotating electric fields depending on time. To do so we solve the Dirac equation for two-component fields in a WKB-likeExpand

On the pair electromagnetic pulse of a black hole with electromagnetic structure
We study the relativistically expanding electron- positron pair plasma formed by the process of vacuum polar- ization around an electromagnetic black hole (EMBH). Such processes can occur for EMBH'sExpand

How universe evolves with cosmological and gravitational constants
Abstract With a basic varying space–time cutoff l ˜ , we study a regularized and quantized Einstein–Cartan gravitational field theory and its domains of ultraviolet-unstable fixed point g ir ≳ 0 andExpand

Euler-Heisenberg Lagrangian and photon circular polarization
Considering the effective Euler-Heisenberg Lagrangian, i.e., nonlinear photon-photon interactions, we study the circular polarization of electromagnetic radiation based on the time evolution ofExpand

Fermionic current and Schwinger effect in de Sitter spacetime
We study the fermionic Schwinger effect in two-dimensional de Sitter spacetime. To do so, we first present a method to semiclassically compute the number of pairs created per momentum mode forExpand

Einstein-Euler-Heisenberg theory and charged black holes
Taking into account the Euler-Heisenberg effective Lagrangian of one-loop nonperturbative quantum electrodynamics (QED) contributions, we formulate the Einstein-Euler-Heisenberg theory and study theExpand

Motivated by the theoretical paradox between the parity-violating gauge symmetries of the standard model and the fundamental regulator, we propose that the extension of the standard model to theExpand

A model of interacting dark fluids tested with supernovae and Baryon Acoustic Oscillations data
Abstract We compare supernovae and Baryon Acoustic Oscillations data to the predictions of a cosmological model of interacting dark matter and dark energy. This theoretical model can be derived fromExpand
