Energy-dependent slow collective flavor conversion of supernova neutrinos
Heng-Hao Chen, Ian Padilla-Gay, Meng-Ru Wu +2
We study collective slow flavor conversion (SFC) of supernova neutrinos with multi-energy, multi-angle simulations for three representative neutrino spectra in the early accretion,…
Neutrino quantum kinetics for fast flavor conversion in a time-dependent environment
Zewei Xiong, Meng-Ru Wu
Fast flavor conversions (FFCs) of neutrinos, driven by the fast flavor instability (FFI), can reshape the neutrino flavor content in dense astrophysical environments such as core-c…
Machine Learning Detection of Non-Axisymmetric Fast Flavor Instabilities in Compact Objects
Madhurima Chakraborty, Sajad Abbar, Meng-Ru Wu +2
Neutrinos in dense astrophysical environments such as core-collapse supernovae (CCSNe) and neutron star mergers (NSMs) can undergo FFCs, which could develop on extremely small scal…
Occurrence of fast neutrino flavor conversions in QCD phase-transition supernovae
Zewei Xiong, Meng-Ru Wu, Noshad Khosravi Largani +2
Core-collapse supernovae undergoing a first-order quantum chromodynamics (QCD) phase transition experience the collapse of the central proto-neutron star that leads to a second bou…
Flavor Equilibration of Supernova Neutrinos: Exploring the Dynamics of Slow Modes
Ian Padilla-Gay, Heng-Hao Chen, Sajad Abbar +2
Neutrinos experience collective flavor conversion in extreme astrophysical environments such as core-collapse supernovae (CCSNe). One manifestation of collective conversion is slow…
Evolution and the quasistationary state of collective fast neutrino flavor conversion in three dimensions without axisymmetry
Manu George, Zewei Xiong, Meng-Ru Wu +1
We investigate in this work the evolution of the collective fast neutrino flavor conversion (FFC) in a three dimensional (3D) cubic box with periodic boundary condition for three d…
Robust integration of fast flavor conversions in classical neutrino transport
Zewei Xiong, Meng-Ru Wu, Manu George +1
The quantum kinetic evolution of neutrinos in dense environments, such as the core-collapse supernovae or the neutron star mergers, can result in fast flavor conversion (FFC), pres…
Fast neutrino flavor conversions in a supernova: Emergence, evolution, and effects
Zewei Xiong, Meng-Ru Wu, Manu George +4
Fast flavor conversions (FFCs) of neutrinos, which can occur in core-collapse supernovae (CCSNe), are multiangle effects. They depend on the angular distribution of the neutrino's…
Application of Neural Networks for the Reconstruction of Supernova Neutrino Energy Spectra Following Fast Neutrino Flavor Conversions
Sajad Abbar, Meng-Ru Wu, Zewei Xiong
Neutrinos can undergo fast flavor conversions (FFCs) within extremely dense astrophysical environments such as core-collapse supernovae (CCSNe) and neutron star mergers (NSMs). In…
Physics-Informed Neural Networks for Predicting the Asymptotic Outcome of Fast Neutrino Flavor Conversions
Sajad Abbar, Meng-Ru Wu, Zewei Xiong
In the most extreme astrophysical environments, such as core-collapse supernovae (CCSNe) and neutron star mergers (NSMs), neutrinos can undergo fast flavor conversions (FFCs) on ex…
