Abstract
In this paper we consider a quintom model of dark energy with a single scalar field given by a Lagrangian which inspired by tachyonic Lagrangian in string theory. We consider non-minimal coupling of tachyon field to the scalar curvature, then we obtain the equation of state (EoS), and the condition required for the model parameters when crosses over -1.
