Subject: Fast neutrino oscillations in supernovae
(Note Special Time)

Neutrinos dominate the energetics of core-collapse supernovae and are crucial to the evolution of the nascent neutron star. An important question of supernova physics is whether neutrino oscillations can occur deep enough in the supernova envelope to have a significant impact on the nucleosynthesis and even the shock revival of the supernova. It was pointed out recently that neutrino oscillations can occur on very short distance/time scales and even in the limit of (almost) zero neutrino masses. I will discuss the mechanism of this fast neutrino oscillation phenomenon and how one may understand it with a few simple but insightful toy models.
