Bijan Saha
TL;DR
This paper models various types of perfect fluids and dark energy in the universe using a nonlinear spinor field, demonstrating their effects on the evolution of a Bianchi type-I universe.
Contribution
It introduces a spinor field framework to simulate different matter characteristics influencing cosmic evolution, providing new insights into anisotropic universe models.
Findings
Nonlinear spinor fields can effectively model perfect fluids and dark energy.
Different matter types influence Bianchi type-I universe evolution distinctly.
The approach offers a unified spinor-based method for cosmological matter simulation.
Abstract
Different characteristic of matter influencing the evolution of the Universe has been simulated by means of a nonlinear spinor field. Using the nonlinear spinor field corresponding to different types of perfect fluid or dark energy as a source of gravitational field, evolution of a Bianchi type-I universe has been illustrated.
