Black Hole Evaporation Driven by Non-Thermal Squeezing Through SNS and CSNS Dynamics
Dhwani Gangal, K. K. Venkataratnam
In this work, we present a comprehensive semiclassical analysis of black hole radiation in a spatially flat FRW Universe for two fundamental nonclassical states: the Squeezed Numbe…
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…
