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…
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…
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…
Ellipsoidal Universe Can Solve The CMB Quadrupole Problem
L. Campanelli, P. Cea, L. Tedesco
The recent three-year WMAP data have confirmed the anomaly concerning the low quadrupole amplitude compared to the best-fit ΛCDM prediction. We show that, allowing the large-scale…
Dynamics of Walls: Fermion Scattering in Magnetic Field
L. Campanelli, P. Cea, G. L. Fogli +1
We investigate the scattering of fermions off walls in the presence of a magnetic field. We consider both the bubble wall and the kink domain wall. By solving the Dirac equation fo…
Influence of the Magnetic Field on the Fermion Scattering off Bubble and Kink Walls
P. Cea, G. L. Fogli, L. Tedesco
We investigate the scattering of fermions off domain walls at the electroweak phase transition in presence of a magnetic field. We consider both the bubble wall and the kink domain…
