Entanglement in a QFT Model of Neutrino Oscillations

Figure 2

QFT instance (color online). The concurrences 𝐶^{(𝜈𝑒;𝜈𝜇)} (full line) and 𝐶^{(𝜈𝑒;𝜈𝜇)} (dashed line) as functions of the scaled time 𝜏=(𝜔₂−𝜔₁)𝑡. The mixing angle 𝜃 is fixed at the experimental value sin²𝜃=0.314; the parameters 𝑥 and 𝑝 are fixed as 𝑥=10 and 𝑝=5. The concurrence associated with the quantum-mechanical Pontecorvo states (dotted line), that is, Figure 1, is also reported for comparison.
