Supplemental material for "Symmetry breaking due to multi-angle matter-neutrino resonance in neutron star merger remnants" (arXiv: 2403.15532)

Authors: Ian Padilla-Gay, Shashank Shalgar and Irene Tamborra


The animations show the flavor evolution of the benchmark scenarios considered in the paper.

In the single-angle animation, we show:
Left: The time evolution of the oscillated total potential $H_{ee}^{\nu\nu}-H_{xx}^{\nu\nu}+ \lambda$.
Right:The time evolution of the neutrino and antineutrino survival probabilities $P(\nu_{e}\rightarrow \nu_{e})$ and $P(\bar{\nu}_{e}\rightarrow \bar{\nu}_{e})$.

In the multi-angle animations$^*$, we show:
Left: The time evolution of the oscillated total potentials, $H_{ee}^{\nu\nu}(v)-H_{xx}^{\nu\nu}(v) + \lambda$, for the forward $(v=1)$ and the backward $(v=-1)$ angular bins.
Middle: The time evolution of the neutrino and antineutrino angle-integrated survival probabilities $P(\nu_{e}\rightarrow \nu_{e})$ and $P(\bar{\nu}_{e}\rightarrow \bar{\nu}_{e})$.
Bottom: The time evolution of the neutrino and antineutrino angular distributions $\rho_{ee}(v)$ and $\bar{\rho}_{ee}(v)$.
$^*$For the multi-angle runs of the ideal neutrino system, we also provide the 2D projections of the angular dependence of the density matrix elements $\rho_{ij}(\cos{\theta},t)$ and $\bar{\rho}_{ij}(\cos{\theta},t)$.
