Multipole expansion method for supernova neutrino oscillations
arXiv:1407.7861 · doi:10.1088/1475-7516/2014/10/084
Abstract
We demonstrate a multipole expansion method to calculate collective neutrino oscillations in supernovae using the neutrino bulb model. We show that it is much more efficient to solve multi-angle neutrino oscillations in multipole basis than in angle basis. The multipole expansion method also provides interesting insights into multi-angle calculations that were accomplished previously in angle basis.
