Cosmological background torsion inhomogeneities and Lorentz violation in QED
L. C. Garcia de Andrade
A non-minimal photon-torsion axial coupling in the quantum electrodynamics (QED) framework is considered. The geometrical optics in Riemann-Cartan spacetime is considering and a pl…
Gravitational stability of inflatons and torsion in Einstein-Cartan-Klein-Gordon Cosmology
L. C. Garcia de Andrade
Gravitational stability of torsion and inflaton potential in a four-dimensional spacetime de Sitter solution in scalar-tensor cosmology where Cartan torsion propagates is investiga…
Cosmological Background torsion limits from Lorentz violation
L. C. Garcia de Andrade
Cosmological limits on Lorentz invariance breaking in Chern-Simons electrodynamics are used to place limits on torsion. Birefrigence phenomena is discussed by u…
Cosmic Rotation Axis, Birefrigence and Axions to detect Primordial torsion fields
L. C. Garcia de Andrade
Nodland Ralston (PRL,1997) investigated the cosmological anisotropy of electromagnetic fields.In this paper we show that it is possible obtain a torsion correction to Nodland-Ralst…
Supersymmetric Potentials in Einstein-Cartan-Brans-Dicke Cosmology
L. C. Garcia de Andrade
Cosmological inflation is discussed in the realm of Einstein-Cartan-Brans-Dicke (ECBD) gravity by constructing an effective inflaton potential and computing the number of e-folds.I…
Torsion and Quantized Vortices
L. C. Garcia de Andrade
A propagation torsion model for quantized vortices is proposed.The model is applied to superfluids and liquid Helium II.
