Electron-positron pairs in physics and astrophysics: from heavy nuclei to black holes

- R. Ruffini, G. Vereshchagin, S. Xue
- Physics
- 6 October 2009

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 three… Expand

Hierarchy spectrum of SM fermions: from top quark to electron neutrino

- S. Xue
- Physics
- 18 March 2016

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 the… Expand

Semiclassical pair production rate for rotating electric fields

- E. Strobel, S. Xue
- Physics
- 8 December 2014

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-like… Expand

On the pair electromagnetic pulse of a black hole with electromagnetic structure

- R. Ruffini, J. Salmonson, J. R. Wilson, S. Xue
- Physics
- 2 July 1999

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's… Expand

How universe evolves with cosmological and gravitational constants

- S. Xue
- Physics
- 21 October 2014

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 and… Expand

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 of… Expand

Fermionic current and Schwinger effect in de Sitter spacetime

- C. Stahl, E. Strobel, S. Xue
- Physics
- 7 July 2015

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 for… Expand

Einstein-Euler-Heisenberg theory and charged black holes

- R. Ruffini, Y. Wu, S. Xue
- Physics
- 17 July 2013

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 the… Expand

On the standard model and parity conservation

- S. Xue
- Physics
- 18 September 2003

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 the… Expand

A model of interacting dark fluids tested with supernovae and Baryon Acoustic Oscillations data

- D. B'egu'e, C. Stahl, S. Xue
- Physics
- 10 February 2017

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 from… Expand
