Nonlinear electrodynamics in Bianchi spacetimes

Abstract

We study the effects produced by nonlinear electrodynamics in spacetimes conformal to Bianchi metrics. In the presence of Born-Infeld type fields these models accelerate, expand and isotropize. This effect is compared with the corresponding to a linear electromagnetic field; it turns out that for the same geometry, Maxwell fields does not favour inflation as much as Born-Infeld field. The behavior of the nonlinear radiation is analyzed in terms of the equation of state. The energy conditions are analyzed as well, showing that the Born-Infeld field violates the strong energy condition.
