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…
