      "value": "We simulate neutrino-antineutrino oscillations caused by strong magnetic fields in dense matter. With the strong magnetic fields and large neutrino magnetic moments, Majorana neutrinos can reach flavor equilibrium. We find that the flavor equilibration of neutrino-antineutrino oscillations are sensitive to the values of the baryon density and the electron fraction inside the matter. The neutrino-antineutrino oscillations are suppressed in the case of the large baryon density in neutron- (proton)-rich matter. On the other hand, the flavor equilibration occurs when the electron fraction is close to 0.5 even in the large baryon density. From the simulations, we propose a necessary condition for the equilibration of neutrino-antineutrino oscillations in dense matter. We also study whether such a necessary condition is satisfied near the protoneutron star by using results of neutrino hydrodynamic simulations of core-collapse supernovae. In our explosion model, the flavor equilibration would be possible if the magnetic field on the surface of the protoneutron star were larger than <math><msup><mn>10</mn><mn>14</mn></msup><mtext> </mtext><mtext> </mtext><mi>G</mi></math>, which is the typical value of the magnetic fields of magnetars."
