Integrated cosmological memory: A dark-siren method to probe dark energy
Indranil Chakraborty, Sayantan Ghosh, Susmita Jana +2
Gravitational-wave (GW) cosmology is currently bottlenecked by the scarcity of electromagnetic counterparts for bright sirens and the systematic uncertainties of galaxy catalogs fo…

Signatures of asymmetry: Gravitational wave memory and the parity violation
Indranil Chakraborty, Susmita Jana, S. Shankaranarayanan
Einstein's equivalence principle suggests a deep connection between matter and spacetime, prompting the question: if matter violates parity, must gravity? This letter explores the…

Signatures of gravitational wave memory in the radiative process of entangled quantum probes
Subhajit Barman, Indranil Chakraborty, Sajal Mukherjee
In this article, we examine entangled quantum probes in geodesic trajectories in a flat background with a gravitational wave (GW) burst. In particular, these quantum probes are pre…
