We consider toy cosmological models in which a classical, homogeneous, spinor field
provides a dominant or sub-dominant contribution to the energy-momentum tensor of a flat …

Self-consistent solutions to the nonlinear spinor field equations in general relativity are
studied for the case of Bianchi type-I (BI) space-time. It is shown that, for some special type …

We consider a self-consistent system of interacting spinor and scalar fields within the
framework of a Bianchi type-I (BI) cosmological model filled with perfect fluid. The interacting …

We consider a self-consistent system of Bianchi type-I (BI) gravitational field and a binary
mixture of perfect fluid and dark energy given by a cosmological constant. The perfect fluid is …

Abstract The Modified Chaplygin Gas (MCG) model belongs to the class of a unified models
of dark energy and dark matter. In this paper, we have modeled MCG in the framework of f …

We consider the Riemann-Cartan geometry as a basis for the Einstein-Sciama-Kibble theory
coupled to spinor fields: we focus on f (R) and conformal gravities, regarding the flag-dipole …

In this review we discuss the evolution of the universe filled with dark energy with or without
perfect fluid. In doing so we consider a number of cosmological models, namely Bianchi type …

We study Dirac spinors in Bianchi type-I cosmological models, within the framework of
torsional f (R)-gravity. We find four types of results: the resulting dynamic behavior of the …

Within the scope of the Bianchi type VI models, the self-consistent system of nonlinear spinor
field and gravitational fields is considered. Exact self-consistent solutions to the spinor and …

We present a tetrad-affine approach to $ f (\mathcal {Q}) $ gravity coupled to spinor fields of
spin-1/2. After deriving the field equations, we derive the conservation law of the spin …
