Revealing the Quantum Signature of Gravity via Gravitational Waves

Partha Nandi

Can propagating gravitational waves serve as operational probes of the quantum nature of gravity? We address this question by developing a unified theoretical framework that combin…

State-Selective Signatures of Quantum and Classical Gravitational Environments

Partha Nandi, Sankarshan Sahu, Bibhas Ranjan Majhi +1

A unified framework is developed for determining whether a gravitational-wave (GW) background behaves as a classical field or as a genuinely quantum environment. Unified here means…

Spinning into Quantum Geometry: Dirac and Wheeler-DeWitt Dynamics from Stochastic Helicity

Partha Nandi, Partha Ghose, Francesco Petruccione

Spin networks in loop quantum gravity provide a kinematical picture of quantum geometry but lack a natural mechanism for dynamical Dirac-type evolution, while the Wheeler--DeWitt e…

A novel quantum memory effect and thermal modulation in graviton-mediated entanglement

Mainak Dutta, Partha Nandi, Bibhas Ranjan Majhi

A central challenge in probing the quantum nature of gravity is to distinguish effects that are genuinely quantum from those that can be explained classically. In this work, we stu…

Gravitationally induced entanglement at finite temperature: A memory-driven time-crystalline phase?

Mainak Dutta, Partha Nandi, Bibhas Ranjan Majhi

We study the impact of thermal effects on gravity-induced entanglement (GIE) in a system of quantum harmonic oscillators interacting with classical linearly polarized gravitational…

Unveiling gravity's quantum fingerprint through gravitational waves

Partha Nandi, Bibhas Ranjan Majhi

We introduce an innovative method to explore gravity's quantum aspects using a novel theoretical framework. Our model delves into gravity-induced entanglement (GIE) while sidestepp…

Quantum ballet by gravitational waves: Generating entanglement's dance of revival-collapse and memory within the quantum system

Partha Nandi, Bibhas Ranjan Majhi, Nandita Debnath +1

Recent proposals are emerging for the experimental detection of entanglement mediated by classical gravity, carrying significant theoretical and observational implications. In fact…
