... A String-Inspired Quintom Model Of Dark Energy . ... We propose in this paper a quintom model of dark energy with a single scalar field x03C6; given by the lagrangian = - V ( x03C6; ) . ... Theoretically it is a big challenge to the model building of the quintom dark energy. ... This model generalizes the usual?Born-Infeld-type? action for the effective description of tachyon dynamics by adding a term x03C6; x25A1; x03C6; to the usual x2207; x03BC; x03C6; x2207; x03BC; x03C6; in the square root. ...
