Interacting spinor and scalar fields in a Bianchi type-I Universe: Oscillatory solutions

Bijan Saha, Todor Boyadjiev

Self-consistent system of spinor, scalar and BI gravitational fields is considered. Exact solutions to the field equations in terms of volume scale of the BI metric are obtained. E…

Spinor field with induced nonlinearity in a Bianchi type-I Universe

Bijan Saha

Self-consistent solutions to the spinor, scalar and BI gravitational field equations are obtained. The problems of initial singularity and asymptotically isotropization process of…

Nonlinear Spinor Field in Anisotropic Universes

Bijan Saha

Evolution of an anisotropic universe described by a Bianchi type I (BI) model in presence of nonlinear spinor field has been studied by us recently in a series of papers. On offer…

Nonlinear Spinor and Scalar Fields in General Relativity

Bijan Saha, G. N. Shikin

We consider a system of nonlinear spinor and scalar fields with minimal coupling in general relativity. The nonlinearity in the spinor field Lagrangian is given by an arbitrary fun…

Soliton Model of Hydrogen Atom: Resonance Effects

Yu. P. Rybakov, B. Saha

Some first principles that, we believe, could serve as foundation for quantum theory of extended particles are formulated. It is also shown that in the point-like particles limit t…

Electrodymanics of Moving Continuous Media with Toroid Polarization

V. M. Dubovik, B. Saha

With regard to the toroid contributions, a modified system of equations of electrodynamics moving continuous media has been obtained. Alternative formalisms to introduce the toroid…
