Description
Neutrino-neutrino interactions drive a number of flavor transformation phenomena in core-collapse supernovae and neutron star mergers that have been shown to impact the supernova explosion mechanism, production of heavy elements in the ejecta, and observable neutrino signatures. The most prominent of these is the Fast Flavor Instability, which can occur deep inside of these systems inaccessible to other flavor transformation mechanisms. I will present a framework for modeling the fast flavor instability under many-body interactions that is able to fully reproduce both mean-field flavor instabilities and many-body dynamics. I will discuss a parameterized transition from mean-field to many-body interactions and demonstrate the effects on the Fast Flavor Instability.
