Vacuum material properties and Cherenkov radiation in logarithmic electrodynamics
Abstract We study some observational signatures of nonlinearities of the electromagnetic field. First to all we show the vital role played by nonlinearities in triggering a material behavior of the vacuum with $$(\varepsilon > 0, \mu <0)$$ ( ε > 0 , μ < 0 ) , which corresponds to a ferri...
