FRW and Bianchi type I cosmology of f-essence

Understand

F-essence is a generalization of the usual Dirac model with the nonstandard kinetic term.

• In this paper, we introduce a new model of spinor cosmology containing both Ricci scalar and the non minimally coupled spinor fields in its action.
• We have investigated the cosmology with both isotropy and anisotropy, where the equations of motion of FRW and Bianchi type-I spacetimes have been derived and solved numerically.
• Finally the quantization of these models through Wheeler-De Witt (WD) wave function has been discussed.
