Probing the quantum speed limit and entanglement in flavor oscillations of neutrino-antineutrino system in curved spacetime
Abhishek Kumar Jha, Mriganka Dutta, Mayank Pathak +2
We consider a spinning primordial black hole (PBH) described by the Kerr metric in Kerr-Schild polar coordinates. We derive an analytical expression for the four-vector gravitation…
Black hole thermodynamics in modified gravity
Mriganka Dutta, Banibrata Mukhopadhyay
The theory of general relativity is often considered under the framework of modified Einstein gravity to explain different phenomena under strong curvature. The strong curvature ef…
Gravitational Influence on the Quantum Speed Limit in Flavor Oscillations of Neutrino-Antineutrino System
Abhishek Kumar Jha, Banibrata Mukhopadhyay, Mriganka Dutta +2
We investigate the quantum speed limit (QSL) during the time evolution of neutrino-antineutrino system under the influence of the gravitational field of a spinning primordial black…
Influence of gravity on the quantum speed limit in neutrino oscillations
Abhishek Kumar Jha, Mriganka Dutta, Subhashish Banerjee +1
The quantum speed limits (QSLs) determine the minimal amount of time required for a quantum system to evolve from an initial to a final state. We investigate QSLs for the unitary e…
