Inflation driven by dark spinor and Higgs fields
Preview AbstractIn this paper, we consider dark spinor and Higgs fields coupled to gravity and calculate their contributions to the energy density and pressure in Friedmann–Robertson–Walker spacetime. We seek solutions of the fields to yield a de Sitter universe and investigate stability properties of the solutions using linear approximation. We discuss the possibility that the inflationary period of our universe can be described by a combination of the dark spinor and Higgs fields.
