Description

Chiral effects induced by quantum anomalies, such as the chiral magnetic effect, are expected to influence the dynamics of core-collapse supernovae (CCSN). These effects arise in strong magnetic fields and rapid flows, which are common in supernova cores. In this work, we investigate the dynamical relevance of chiral neutrino radiation transport in CCSN, focusing on near-equilibrium contributions to the neutrino radiation energy-momentum tensor based on the formulation of Yamamoto & Yang (2021). Using data from two-dimensional CCSN simulations with neutrino transport, we evaluate the chiral radiation source term. We implement the chiral neutrino radiation term into the FLASH simulation code and investigate its impact on the hydrodynamic evolution, with self-consistent coupling in progress, to explore whether it may contribute to neutron star kicks.
