Quantum speed limit time for bipartite entanglement in neutrino oscillations in matter with non-standard interactions

Abhishek Kumar Jha, Lekhashri Konwar, Rukmani Mohanta

In the three-flavor neutrino oscillation framework, we investigate the transition probabilities of an initial muon neutrino flavor state in the presence of non-standard interaction…

Quantum spread complexity as a probe of NSI, Violation, and mass ordering in neutrino oscillations in matter

Abhishek Kumar Jha, Govind Krishna G, Anandbhai Pravinbhai Prajapati +1

Quantum spread complexity characterizes how a quantum state evolves and becomes distributed over the Hilbert space under unitary dynamics. In this work, we employ a cost function a…

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…

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…
