Maxwell-Kostelecký Electromagnetism and Cosmic Magnetization
L. Campanelli, P. Cea
The Lorentz violating term in the photon sector of Standard Model Extension, $\mathcal{L}_K = -{$\frac14$} (k_F)_{αβμν} F^{αβ} F^{μν}$ (here referred to as the Kostelecký term), br…
Gravitational Radiation from Primordial Helical Inverse Cascade MHD Turbulence
Tina Kahniashvili, Leonardo Campanelli, Grigol Gogoberidze +2
We consider the generation of gravitational waves by primordial helical inverse cascade magnetohydrodynamic (MHD) turbulence produced by bubble collisions at the electroweak phase…
Lorentz Symmetry Violation and Galactic Magnetism
L. Campanelli, P. Cea, G. L. Fogli
We analyze the generation of primordial magnetic fields during de Sitter inflation in a Lorentz-violating theory of Electrodynamics containing a Chern-Simons term which couples the…
Helical Magnetic Fields from Inflation
Leonardo Campanelli
We analyze the generation of seed magnetic fields during de Sitter inflation considering a non-invariant conformal term in the electromagnetic Lagrangian of the form $-\frac14 I(ϕ)…
Inflation-Produced Magnetic Fields in R^n F^2 and I F^2 models
L. Campanelli, P. Cea, G. L. Fogli +1
We re-analyze the production of seed magnetic fields during Inflation in (R/m^2)^n F_{μν}F^{μν} and I F_{μν}F^{μν} models, where n is a positive integer, R the Ricci scalar, m a ma…
Inflation-Produced Magnetic Fields in Nonlinear Electrodynamics
L. Campanelli, P. Cea, G. L. Fogli +1
We study the generation of primeval magnetic fields during inflation era in nonlinear theories of electrodynamics. Although the intensity of the produced fields strongly depends on…
