Good tachyons, bad bradyons: role reversal in Einstein-nonlinear-electrodynamics models
Marco A. A. de Paula, Haroldo C. D. Lima Junior, Pedro V. P. Cunha +2
In relativistic mechanics, the 4-velocity and the 4-momentum need not be parallel. This allows their norm to have a different sign. This possibility occurs in nonlinear electrodyna…
Static boson stars in the Einstein-Friedberg-Lee-Sirlin theory and their astrophysical images
Pedro L. Brito de Sá, Haroldo C. D. Lima, Carlos A. R. Herdeiro +1
We investigate the static boson star solutions in the so-called Einstein-Friedberg-Lee-Sirlin (E-FLS) theory, performing a complete analysis of the solution space in this model. We…
Singular space-times with bounded algebraic curvature scalars
Renan B. Magalhães, Gabriel P. Ribeiro, Haroldo C. D. Lima Junior +2
We show that the absence of unbounded algebraic curvature invariants constructed from polynomials of the Riemann tensor cannot guarantee the absence of strong singularities. As a c…
