Geometrical Generation of Cosmic Magnetic Fields within Standard Electromagnetism
Geometrical Generation Cosmic Magnetic Fields Standard Electromagnetism
2010/10/18
We study the evolution of cosmological magnetic fields in FRW models with curved spatial sections and outline a geometrical mechanism for their superadiabatic amplification on large scales. The mechan...
The Effective Longitudinal Dielectric Constant for Plasmas in Inhomogeneous Magnetic Fields
The Effective Longitudinal Dielectric Constant Plasmas Inhomogeneous Magnetic Fields
