General-Relativistic Quantum-Kinetics Neutrino Transport

Understand

We developed a new general-relativistic quantum-kinetics neutrino transport code, GRQKNT, for numerical studies of quantum kinetics of non-equilibrium neutrinos in six-dimensional phase space.

• This code is intended for use in both local and global simulations of neutrino transport in core-collapse supernova and binary neutron star merger.
• It has been widely recognized that global simulations of collective neutrino oscillations, in particular fast neutrino-flavor conversions (FFC), require unfeasible computational resources due to large disparity of scales between flavor conversion and astrophysical phenomena.
• We propose a novel approach to tackle the issue.
