Quantum nature of gravity and spacetime: Fundamental insights from the Hoyle-Narlikar theory
Dawood Kothawala
The Hoyle-Narlikar action-at-a-distance formulation for gravity remains one of the most mathematically rigorous attempts to incorporate Mach principle into physics. A lesser known,…
When the Ringing Stops: Purely Imaginary Modes in the Ringdown Spectrum of Dynamical Black Holes
Lodovico Capuano, Thomas Lovo, Gorka Prieto-Varela +4
We extend the frequency-domain analysis of quasinormal modes in a dynamical, spherically symmetric black hole spacetime undergoing constant-rate mass evolution. In particular, we r…
Geodesic structure of spacetime near singularities
Mayank, Dawood Kothawala
Geodesic flows emanating from an arbitrary point in a manifold carry important information about the geometric properties of . These flows…
Microcanonical Phase Space and Entropy in Curved Spacetime
Avinandan Mondal, Dawood Kothawala
We discuss the structure of microcanonical ensembles in inertial and non-inertial frames attached to a confined system of positive energy particles in curved spacetime. Under certa…
Twin-paradox and Entanglement
K. Hari, Subhajit Barman, Dawood Kothawala
We study the quantum version of the classical twin paradox in special relativity by replacing the twins with quantum detectors, and studying the transitions and entanglement induce…
Worldline EFT treatment of quadratic and cubic gravity theories
Raghotham A Kulkarni, Rahul, Soham Bhattacharyya +1
This paper explores modifications to General Relativity (GR) by considering higher-order curvature terms in the gravitational action, specifically focusing on the quadratic Ricci s…
