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…

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 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…
