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…
