Action-level characterization of gravitational-wave propagation in dynamical Barbero--Immirzi gravity
Zhi-Fu Gao, Hui Wang, Luiz Carlos Garcia de Andrade +3
We investigate which operators in first-order dynamical Barbero--Immirzi (BI) gravity control cosmological tensor propagation at the action level. Within a bosonic, two-derivative,…
Bayesian Geometrical Modeling of IXPE Polarization Angle Curves of the Magnetars 1E 2259+586 and 1E 1547.0-5408
Biao-Peng Li, Zhi-Fu Gao, Wen-Qi Ma +2
X-ray polarimetry directly probes the radiation geometry and large-scale magnetic configuration of magnetars. We present a uniform Bayesian comparison between a dipole-dominated cl…
Metric-torsion preheating: cosmic dynamo mechanism?
L C Garcia de Andrade
Earlier Bassett et al [Phys Rev D 63 (2001) 023506] investigated the amplification of large scale magnetic fields during preheating and inflation in several different models. They…
Stringent magnetic field limits from early universe dynamos cosmology with torsion
Luiz Carlos Garcia de Andrade
Earlier Bamba et al [JCAP (2012)] have obtained cosmological magnetic fields in teleparallel torsion theories of gravity that are not compatible with galactic dynamos. This result…
Anosov branches of dynamo spectra in one dimensional plasmas
L. C. Garcia de Andrade
Recently Guenther et al the globally diagonalized dynamo operator spectrum [J Phys A 2007) in mean field media, and its Krein space related perturbation theory [J Phys A 20…
Mean-field cosmological dynamo curvature vs turbulence spectrum in Riemannian space
L Garcia de Andrade
Previous attempts for building a cosmic dynamo including preheating in inflationary universes [Bassett et al Phys Rev (2001)] has not included mean field dynamos. Here, a mean fiel…
Primordial magnetic fields constrained by CMB anisotropies and dynamo cosmology
Garcia de Andrade
Magneto-curvature stresses could deform magnetic field lines and this would give rise to back reaction and restoring magnetic stresses [Tsagas, PRL (2001)]. Barrow et al [PRD (2008…
