Abstract:
It is known that the neutrinos can oscillate collectively in astrophysical and cosmological environments that are dense in neutrinos, despite their weakly interacting nature. Studies in recent years revealed that core-collapse supernovae and neutron star mergers generally host conditions for the so-called "fast" neutrino flavor conversions to happen, such that neutrinos can change their flavors in length scales of sub centimeters. In this talk, I will first introduce the conditions and the potential implications of collective fast neutrino oscillations. I will then discuss our recent efforts in developing numerical simulation codes that aim to solve the quantum transport equations of neutrinos in astrophysical context.
