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…
Quantum Geometric Phases as a New Window on Gravitational Waves
Partha Nandi, Frederik G. Scholtz
We investigate how low-frequency gravitational waves (LFGWs), originating from distant astrophysical or cosmological sources, can induce purely quantum geometric phases in mesoscop…
Can Non-Relativistic Strings Propagate Without Geometric Baggage?
Partha Nandi, Sk. Moinuddin, Abdus Sattar
We present a minimal and dynamically consistent formulation of non-relativistic bosonic string theory in a Newton-Cartan (NC) background. Starting from a reparametrization-invarian…
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…
