Cosmic Structure Formation in a Viable Power-Law f(R) Gravity Model: Growth Dynamics, Stability, and Observational Signatures
Murli Manohar Verma
We investigate the evolution of cosmic structures in the power-law modified gravity model , where the dimensionless parameter characterizes deviations fro…
Cosmological wheel or the arrow of time: A classical versus quantum perspective of gravity
Bal Krishna Yadav, Murli Manohar Verma
It is shown that the structures in the universe can be interpreted to show a closed wheel of time, rather than a straight arrow. An analysis in gravity model has been carrie…
Cosmological arrow of time in f(R) gravity
Bal Krishna Yadav, Murli Manohar Verma
The cosmological arrow of time may be linked to the thermodynamic arrow by second law of thermodynamics. The time asymmetry is also associated with dissipative fluid as Tolman intr…
A tachyonic scalar field with mutually interacting components
Murli Manohar Verma, Shankar Dayal Pathak
We investigate the tachyonic cosmological potential in two different cases of the quasi-exponential expansion of universe and discuss various forms of interaction between th…
