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…
Droplet-like Solutions to the Nonlinear Scalar Field Equations in the Robertson-Walker Space-time and their Stability
Yu. P. Rybakov, B. Saha, G. N. Shikin
Exact droplet-like solutions to the nonlinear scalar field equations have been obtained in the Robertson-Walker space-time and their linearized stability has been proved.
Exact Self-consistent Solutions to the Interacting Spinor and Scalar Field Equations in Bianchi Type-I Space-time
R. Alvarado, Yu. P. Rybakov, B. Saha +1
Self-consistent solutions to the system of spinor and scalar field equations in General Relativity are studied for the case of Bianchi type-I space-time. It should be emphasized th…
Droplets in General Relativity: Exact Self-Consistent Solutions to the Interacting Scalar and Electromagnetic Field Equations
Yu. P. Rybakov, B. Saha, G. N. Shikin
It is shown, for the self-consistent system of scalar, electro-magnetic and gravitational fields in general relativity, that the equations of motion admit a special kind of solutio…
