Gravitational wave detection via photon-graviton scattering and quantum interference
K. Hari, S. Shankaranarayanan
We present a fully quantum field-theoretic framework for gravitational wave (GW) detection in which the interaction is described as photon-graviton scattering. In this picture, the…
Quantum Cosmology as a Hydrogen atom: Discrete and cyclic Universes from Wheeler-DeWitt quantization
Dipayan Mukherjee, Harkirat Singh Sahota, S. Shankaranarayanan
Building upon our recently established correspondence between quantum cosmology and the hydrogen atom [1], we investigate the specific sector of a negative cosmological constant ($…
Covariant Carrollian Electric and Magnetic Limits of General Relativity
Tanmay Patil, S. Shankaranarayanan
The Carrollian limit () of General Relativity provides the geometric language for describing null hypersurfaces, such as black hole event horizons and null infinity. Motiv…
Axial quasi-normal modes of slowly rotating black holes in dynamical Chern-Simons gravity to second-order in spin and coupling
Tharaka Alapati, S. Shankaranarayanan
We compute the quasi-normal mode (QNM) frequencies of slowly rotating black holes in dynamical Chern-Simons (dCS) gravity, including corrections up to second order in the black hol…
