Distinguishing between Dirac and Majorana neutrinos using temporal correlations
Bhavya Soni, Sheeba Shafaq, Poonam Mehta
In the context of two flavour neutrino oscillations, it is understood that the mixing matrix is parameterized by one angle and a Majorana phase. However, this phase doe…
Investigating Leggett-Garg inequality in neutrino oscillations -- role of decoherence and decay
Sheeba Shafaq, Tanmay Kushwaha, Poonam Mehta
Neutrinos, due to their weakly interacting nature, provide us with a unique opportunity to test foundations of quantum mechanics over macroscopic distances. There has been consider…
Physics prospects with the second oscillation maximum at Deep Underground Neutrino Experiment
Jogesh Rout, Sheeba Shafaq, Mary Bishai +1
Current long-baseline neutrino-oscillation experiments such as NOA and T2K are mainly sensitive to physics in the neighbourhood of the first oscillation maximum of the $ν_μ\to ν…
Enhanced violation of Leggett-Garg Inequality in three flavour neutrino oscillations via non-standard interactions
Sheeba Shafaq, Poonam Mehta
Neutrino oscillations occur due to non-zero masses and mixings and most importantly they are believed to maintain quantum coherence even over astrophysical length scales. In the pr…
Wave-Packet Analysis of Single-Slit Ghost Diffraction
Tabish Qureshi, Sheeba Shafaq
We show that single-slit two-photon ghost diffraction can be explained very simply by using a wave-packet evolution of a generalised EPR state. Diffraction of a wave travelling in…
Understanding Ghost Interference
Tabish Qureshi, Pravabati Chingangbam, Sheeba Shafaq
The ghost interference observed for entangled photons is theoretically analyzed using wave-packet dynamics. It is shown that ghost interference is a combined effect of virtual doub…
Theoretical Analysis of Two-Color Ghost Interference
Sheeba Shafaq, Tabish Qureshi
Recently demonstrated ghost interference using correlated photons of different frequencies, has been theoretically analyzed. The calculation predicts an interesting nonlocal effect…
