The Gravitational Spectral Radio Forest: A Signature of Primordial Black Holes
P. George Christopher, K. Hari, S. Shankaranarayanan
We propose a novel gravitational signature to detect Primordial Black Hole (PBH) dark matter by treating interstellar hydrogen as a quantum sensor for spacetime curvature. Focusing…
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…
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…
Radiative process of tripartite entangled probes in inertial motion
Subhajit Barman, K. Hari
We study the radiative process of three entangled quantum probes initially prepared in a tripartite W state. As a basic set-up, we consider the probes to be inertial in flat spacet…
Entanglement between accelerated probes in a de Sitter spacetime
Mayank, K. Hari, Subhajit Barman +1
We initiate an investigation into features of vacuum entanglement as probed by accelerated quantum probes in curved spacetime. Focussing specifically on de Sitter (dS) spacetime wi…
Searching for stochastic gravitational waves using data from the two co-located LIGO Hanford detectors
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +873
Searches for a stochastic gravitational-wave background (SGWB) using terrestrial detectors typically involve cross-correlating data from pairs of detectors. The sensitivity of such…
