Nonlinear evolution of fast neutrino flavor conversion in the preshock region of core-collapse supernovae

Masamichi Zaizen, Taiki Morinaga

In environments with high dense neutrino gases, such as in core-collapse supernovae, the neutrinos can experience collective neutrino oscillation due to their self-interactions. In…

Spatiotemporal linear instability analysis of collective neutrino flavor conversion in 4-dimensional spacetime

Taiki Morinaga

In an environment with high-density neutrinos formed in a core-collapse supernova (CCSN), the neutrinos exhibit nonlinear and complex oscillation behaviors due to their self-intera…

Spatio-temporal linear instability analysis for arbitrary dispersion relations on the Lefschetz thimble in multidimensional spacetime

Taiki Morinaga, Shoichi Yamada

In linear stability analysis of field quantities described by partial differential equations, the well-established classical theory is all but impossible to apply to concrete probl…

Fast-pairwise collective neutrino oscillations associated with asymmetric neutrino emissions in core-collapse supernova

Hiroki Nagakura, Taiki Morinaga, Chinami Kato +1

We present a linear stability analysis of the fast-pairwise neutrino flavor conversion based on a result of our latest axisymmetric core-collapse supernova (CCSN) simulation with f…

Fast collective neutrino oscillations inside the neutrino sphere in core-collapse supernovae

Milad Delfan Azari, Shoichi Yamada, Taiki Morinaga +6

Neutrinos are believed to have a key role in the explosion mechanism of core-collapse supernovae as they carry most of the energy released by the gravitational collapse of a massiv…

A new possibility of the fast neutrino-flavor conversion in the pre-shock region of core-collapse supernova

Taiki Morinaga, Hiroki Nagakura, Chinami Kato +1

We make a strong case that the fast neutrino-flavor conversion, one of the collective flavor oscillation modes, commonly occurs in core-collapse supernovae (CCSNe). It is confirmed…
