Schwarzschild-like metric and a quantum vacuum
P. R. Silva
A quantum vacuum, represented by a viscous fluid, is added to the Einstein vacuum, surrounding a spherical distribution of mass. This gives as a solution, in spherical coordinates,…
Relic neutrinos and cosmic background radiation: a new way of comparison
P. R. Silva
A new equation of state is proposed in order to describe the thermal behavior of relic neutrinos. It is based on extensions of the MIT bag model to deal with the gravitational inte…
Analysis of the mass structure of the hadrons
P. R. Silva
Inspired in previous works of Xiangdong Ji, published in PRL and PRD in 1995, we worked out an alternative way to separate within the structure of QCD, the hadron masses into contr…
Decoherence and coherence in gravitational, electric and strong nuclear fields
P. R. Silva
Inspired in the work of Erich Joos which appreciated the role played by matter in making the decoherence of the gravitational field, we developed an alternative way of treating the…
High Temperature Superconductivity in Cuprates: a model
P. R. Silva
A model is proposed such that quasi-particles (electrons or holes) residing in the CuO2 planes of cuprates may interact leading to metallic or superconducting behaviors. The metall…
Gravitational effectiveness of the zero-point energy of the radiation field: a possible solution of a paradox raised by Pauli
P. R. Silva
A modified vacuum energy density of the radiation field is evaluated, which leads to accepted prediction for the radius of the universe. The modification takes into account the exi…
