Code Comparison for Fast Flavor Instability Simulation
Sherwood Richers, Huaiyu Duan, Meng-Ru Wu +5
The fast flavor instability (FFI) is expected to be ubiquitous in core-collapse supernovae and neutron star mergers. It rapidly shuffles neutrino flavor in a way that could impact…
Fast Neutrino Flavor Conversion Modes in Multidimensional Core-collapse Supernova Models: the Role of the Asymmetric Neutrino Distributions
Sajad Abbar, Huaiyu Duan, Kohsuke Sumiyoshi +2
A dense neutrino gas, such as the one anticipated in the supernova environment, can experience fast neutrino flavor conversions on scales much shorter than those expected in vacuum…
On the occurrence of fast neutrino flavor conversions in multidimensional supernova models
Sajad Abbar, Huaiyu Duan, Kohsuke Sumiyoshi +2
The dense neutrino medium in a core-collapse supernova or a neutron-star merger event can experience fast flavor conversions on time/distance scales that are much smaller than thos…
Neutrino flavor instabilities in a time-dependent supernova model
Sajad Abbar, Huaiyu Duan
A dense neutrino medium such as that inside a core-collapse supernova can experience collective flavor conversion or oscillations because of the neutral-current weak interaction am…
Quantum Monte Carlo calculations of the thermal conductivity of neutron star crusts
Sajad Abbar, Joe Carlson, Huaiyu Duan +1
We use the quantum Monte Carlo (QMC) techniques to calculate the static structure function of a one-component ion lattice and use it to calculate the thermal conductivity $κ…
Neutrino Luminosity and Matter-Induced Modification of Collective Neutrino Flavor Oscillations in Supernovae
John F. Cherry, Meng-Ru Wu, Joe Carlson +3
We show that the bump in the electron number density profile at the base of the hydrogen envelope in O-Ne-Mg core-collapse supernovae causes an interesting interplay between neutri…
