Non-minimally coupled galileon like scalar field model -- A Dynamical System Analysis

Year: 2015

Type: preprint

Abstract: We consider a Galileon-like scalar field non-minimally coupled to gravity to construct a model of dark energy. The system is dynamically analyzed and novel fixed points with perturbative stability are demonstrated. The evolution of the system is tracked with r-s statefinder parameters. We also observe that the model allows the phantom crossing without requiring the non-canonical kinetic energy term.
