Dynamical equilibria of fast neutrino flavor conversion
Jiabao Liu, Lucas Johns, Hiroki Nagakura +2
Dense neutrino systems, which display collectivity mediated by the weak interaction, have deep parallels with mean-field kinetic systems governed by other fundamental forces. We id…
The Effect of the Collisional Flavor Instability on Core-Collapse Supernova Models
Tianshu Wang, Hiroki Nagakura, Lucas Johns +1
We explore the effects of the neutrino collisional flavor instability (CFI) based on 1D and 2D core-collapse supernova (CCSN) simulations done using the sophisticated radiation-hyd…
Asymptotic states of fast neutrino-flavor conversions in the three-flavor framework
Jiabao Liu, Hiroki Nagakura, Masamichi Zaizen +2
There has been growing evidence that mu and tau neutrinos are noticeably different due to the emergence of muons in core-collapse supernovae (CCSNe) and binary neutron star mergers…
Resolution requirements for numerical modeling of neutrino quantum kinetics
Hiroki Nagakura, Masamichi Zaizen, Jiabao Liu +1
Neutrino quantum kinetics is a rapidly evolving field in computational astrophysics, with a primary focus on collective neutrino oscillations in core-collapse supernovae and post-m…
Quasi-steady evolution of fast neutrino-flavor conversions
Jiabao Liu, Hiroki Nagakura, Masamichi Zaizen +3
In astrophysical environments such as core-collapse supernovae (CCSNe) and binary neutron star mergers (BNSMs), neutrinos potentially experience substantial flavor mixing due to th…
BGK subgrid model for neutrino quantum kinetics
Hiroki Nagakura, Lucas Johns, Masamichi Zaizen
We present a new subgrid model for neutrino quantum kinetics, which is primarily designed to incorporate effects of collective neutrino oscillations into neutrino-radiation-hydrody…
Collisional flavor swap with neutrino self-interactions
Chinami Kato, Hiroki Nagakura, Lucas Johns
Neutrinos play pivotal roles in determining fluid dynamics, nucleosynthesis, and their observables in core-collapse supernova (CCSN) and binary neutron star merger (BNSM). In this…
