On a Separatrix in the Gravitational Collapse to an Overcritical Electromagnetic Black Hole

R. Ruffini, L. Vitagliano, S. -S. Xue

The dynamical properties of an electron--positron--photon plasma created by the vacuum polarization process occurring around a charged gravitationally collapsing core of an initial…

Vector-like Fermion Doubling and Pair-creation on a lattice

She-Sheng Xue

Based on the Pauli principle and Heisenberg uncertainty relationship, we show that the phenomenon of vectorlike fermion-doubling in quantum field theories on a lattice is related t…

GRB 980425, SN1998bw and the EMBH model

Remo Ruffini, Maria Grazia Bernardini, Carlo Luciano Bianco +3

The EMBH model, previously developed using GRB 991216 as a prototype, is here applied to GRB 980425. We fit the luminosity observed in the 40-700 keV, 2-26 keV and 2-10 keV bands b…

Plasma expansion in the geometry of a collapsing star

R. Ruffini, L. Vitagliano, S. -S. Xue

We describe the evolution of an electron-positron-photon plasma created by Sauter--Heisenberg--Euler--Schwinger mechanism around a collapsing charged star core in the Reissner-Nord…

electron-positron-photon plasma around a collapsing star

R. Ruffini, L. Vitagliano, S. -S. Xue

We describe electron-positron pairs creation around an electrically charged star core collapsing to an electromagnetic black hole (EMBH), as well as pairs annihilation into photons…

On Plasma Oscillations in Strong Electric Fields

R. Ruffini, L. Vitagliano, S. -S. Xue

We describe the creation and evolution of electron-positron pairs in a strong electric field as well as the pairs annihilation into photons. The formalism is based on generalized V…
