Entanglement in a QFT Model of Neutrino Oscillations

Figure 3

QFT instance (color online). In (a) the concurrences 𝐶^{(𝜈𝑒;𝜈𝑒)} (full line) and 𝐶^{(𝜈𝜇;𝜈𝑒)} (dashed line), in (b) the concurrences 𝐶^{(𝜈𝑒;𝜈𝜇)} (full line) and 𝐶^{(𝜈𝜇;𝜈𝜇)} (dashed line), as functions of the scaled time 𝜏=(𝜔₂−𝜔₁)𝑡. The mixing angle 𝜃 and the parameters 𝑥 and 𝑝 are fixed as in Figure 2.
