CORRESPONDENCE BETWEEN ELECTROMAGNETIC FIELD AND OTHER DARK ENERGIES IN NONLINEAR ELECTRODYNAMICS
Abstract
In this work, we have considered the flat FRW model of the universe filled with electromagnetic field. First, the Maxwell's electromagnetic field in linear form has been discussed and after that the modified Lagrangian in nonlinear form for accelerated universe has been considered. The corresponding energy density and pressure for nonlinear electromagnetic field have been calculated. We have found the condition such that the electromagnetic field generates dark energy. The correspondence between the electromagnetic field and the other dark energy candidates namely tachyonic field, DBI-essence, Chaplygin gas, hessence dark energy, k-essence and dilaton dark energy have been investigated. We have also reconstructed the potential functions and the scalar fields in this scenario.
