EXACT SOLUTIONS IN COSMOLOGICAL MODELS WITH NON-MINIMAL COUPLING OF SCALAR FIELD AND TORSION
Dentsel E.S., Fomin I.V.
Cosmological inflation models with scalar field based on teleparallel gravity with non-minimal coupling of scalar field and torsion are considered. Solution type obtained in this paper is justified for any Hubble parameter and scalar field evolution. Also, the model with scalar field potenital \(V(\phi) = \frac{m^2}{2}\phi^n \), relating to chaotic inflation with massive scalar field, is verified by modern restrictions on values of cosmological perturbations parameters.
Keywords: teleparallel gravity, torsion, scalar fields, exact solutions, chaotic inflation.
