超新星中微子味演化的数值和物理稳定性

Numerical and Physical Stability of Supernova Neutrino Flavor Evolution

B. D. Keister

摘要:

本文研究了中微子味超新星中微子球外的演化使用一维模型,保留了中微子中微子相互作用的非线性性质,以及一些方面的完整的几何。在某些极限情况下,分析结果可以显示出与(线性)太阳中微子味演化中的对应物不同的行为。对于更一般的情况,数值解需要扩展的数值算法来实现稳定的解决方案,这些解决方案表现出标准的混沌行为。

英文摘要:

This paper examines neutrino flavor evolution outside a supernova neutrinosphere using a one-dimensional model that retains the non-linear nature of neutrino-neutrino interactions as well as some aspects of the full geometry. In some limiting cases analytic results can be obtained that display different behavior from their counterparts in (linear) solar neutrino flavor evolution. For more general cases, numerical solutions require extended numerical algorithms to achieve stable solutions, and these solutions exhibit standard chaotic behavior.
