Relativistic Signatures of Dark Matter Equations of State in Static Spherically Symmetric Spacetimes
Akash Yadav, Sudhava Yadav, K. K. Venkataratnam
We study how three physically motivated dark matter equations of state alter the spacetime geometry of static, spherically symmetric black holes in General Relativity. The models c…
Reheating study of Mexican-Hat-type Potentials
Sudhava Yadav, Akash Yadav, K. K. Venkataratnam
We study reheating in Mexican Hat type potentials, emphasizing the role of the post-inflationary equation-of-state parameter() in shaping observable predi…
Investigation of Super-Poissonian Nonclassical Nature of Inflaton Field in Flat FRW Universe through Cosmological Mandels Parameter
Dhwani Gangal, Sudhava Yadav, K. K. Venkataratnam
This study investigates the nonclassical properties of the inflaton field within the framework of semiclassical gravity by analyzing Cosmological Mandels parameter for Squeezed…
Particle Production and Density Fluctuations of Non-classical Inflaton in Coherent Squeezed Vacuum State of Flat FRW Universe
Dhwani Gangal, Sudhava Yadav, K. K. Venkataratnam
We study non-classical inflaton, which is minimally coupled to the semiclassical gravity in FRW universe in Coherent Squeezed Vacuum State (CSVS). We determined Oscillatory phase o…
Density fluctuations for Squeezed Number State and Coherent Squeezed Number State in Flat FRW Universe
Dhwani Gangal, Sudhava Yadav, K. K. Venkataratnam
We study the density fluctuations for Coherent Squeezed Number State (CSNS) and Squeezed Number States (SNS) formalism in Semiclassical theory of grav ity in flat FRW universe. We…
Reheating constraints on mutated hilltop inflation
Sudhava Yadav, Dhwani Gangal, K. K. Venkataratnam
Future research studies of cosmic microwave background polarization seems likely to provide a more improved upper bound of on the tensor-to-scalar ratio(r). In our wor…
Reheating constraints on modified quadratic chaotic inflation
Sudhava Yadav, Rajesh Goswami, K. K Venkataratnam +1
The Reheating era of inflationary universe can be parameterized by various parameters like reheating temperature \(T_{\text{re}}\), reheating duration \(N_{\text{re}}\) and average…
