论文摘要
我们研究了一些最极端的天体物理部位，例如中子星级合并残余物和磁性旋转核心偏转超新星，包括密集的中微子培养基，在存在强磁场的情况下，其中包括密集的中微子培养基。我们表明，如果中微子过渡力矩$μ_ν$足够强，即当$μ_ν/μ__ {\ rm {b}} \ gtrsim 10^{ - 14} -10} -10^{ - 15} $带有$μ__ {b rmm {b rmm mann} $这种风味平衡不一定是风味的均衡，可以在（短）尺度上发生，由磁性项的强度确定。我们的发现可能对这种暴力天体物理环境的物理学具有有趣的影响。
We study collective oscillations of Majorana neutrinos in some of the most extreme astrophysical sites such as neutron star merger remnants and magneto-rotational core-collapse supernovae which include dense neutrino media in the presence of strong magnetic fields. We show that neutrinos can reach flavor equilibrium if neutrino transition magnetic moment $μ_ν$ is strong enough, namely when $μ_ν/μ_{\rm{B}} \gtrsim 10^{-14}-10^{-15}$ with $μ_{\rm{B}}$ being the Bohr magneton. This sort of flavor equilibrium, which is not necessarily flavor equipartition, can occur on (short) scales determined by the strength of the magnetic term. Our findings can have interesting implications for the physics of such violent astrophysical environments.
