Varying Gravitational Constant as Well as Cosmology from the Early Inflation to Late Acceleration and Future Universe
S. K. Srivastava
Here, cosmology is obtained from the variable gravitational constant with being a scalar and its fluctuations around the ground state. The gravitationa…
-Cosmolgy from Early Universe Upto Future Cosmic Collapse and its Avoidance
S. K. Srivastava
In the present model, a unified picture of cosmology from early inflation to late acceleration is obtained from gravity with non-linear terms and of scalar…
Gravitational Origin of Phantom Dark Energy and Late Cosmic Acceleration
S. K. Srivastava
In this letter, dark energy is obtained using dual roles of the Ricci scalar (as a physical field as well as geometry). Dark energy density, obtained here, mimics phantom and the d…
Early and Late Transient Cosmic Acceleration due to Curvature Inspired Dark Energy
S. K. Srivastava
It is obtained that dark energy emerges from higher-derivative gravity with anon-linear terms proportional to and with being the Ricci scalar curvature. Interesting…
Quintessence Dark Energy Inspired by Dual Role of the Ricci Scalar
S. K. Srivastava
In this letter, it is obtained using dual role of the Ricci scalar (physical as well as geometrical role of the Ricci scalar curvature) in a natural way without any input in the th…
Dark Energy and dark matter of the universe from one-loop renormalization of riccion
S. K. Srivastava
Here, creation of the universe is obtained only from gravity sector. The dynamical universe begins with two basic ingredients (i) vacuum energy, also called dark energy (as vacuum…
