Origins of Thermalization in Semiclassical Cosmology
Michael Osei, Arundhati Dasgupta
We discuss the effect of `Rindler like' transformation in superspace on the WKB wavefunction in cosmology. In the transformed frame we find the density matrix of the WKB wavefuncti…
Aspects of Quantum Gravity Phenomenology and Astrophysics
Arundhati Dasgupta, José Fajardo-Montenegro
With the discovery of gravitational waves, the search for the quantum of gravity, the graviton, is imminent. We discuss the current status of the bounds on graviton mass from exper…
Interaction of Gravitational Waves with Yang-Mills fields
Narasimha Reddy Gosala, Arundhati Dasgupta
In this paper, we discuss the interaction of non-Abelian SU(2) Yang-Mills progressive waves with gravitational waves. We solve and obtain some interesting solutions to pure Yang-Mi…
Interaction of Electromagnetic field with a Gravitational wave in Minkowski and de-Sitter space-time
Akash Patel, Arundhati Dasgupta
It is important to re-examine some of the interactions of gravitational waves with matter due to the recent discovery of the waves in LIGO. In a previous paper with Morales, intera…
Semiclassical corrections to the photon orbits of a non-rotating black hole
Swayamsiddha Maharana, Arundhati Dasgupta
In this brief article we discuss the corrections to the photon orbits of a non-rotating black hole due to semiclassical fluctuations of the metric. It is found that the photon orbi…
Scalar and Fermion field interactions with a gravitational wave
Siddhartha E. Morales G., Arundhati Dasgupta
Given that gravitational waves are the future probes of the universe, it is important to test various physical effects of these on matter. This article explores the first-order per…
