Subject: Collective oscillations of dense neutrino gas

We study collective two-flavor oscillations of an isotropic gas of monochromatic neutrinos and antineutrinos. We analytically solve for the eigenstates at fixed neutrino density and perform stability analyses of these states. We use the stable eigenstates to understand the flavor evolution of the dense neutrino gas above the proto-neutron star in a core-collapse supernova or above the accretion disk in a neutron-star merger.
