Abstract: We study the effect of gravity on neutrino flavor oscillations when each mass eigenstate is described by a wave packet instead of a plane wave. Two different approaches for implementing the wave packet formalism in… read more here.

DOI: 10.1103/physrevd.103.083014
Abstract: In an environment with high-density neutrinos formed in a core-collapse supernova (CCSN), the neutrinos exhibit nonlinear and complex oscillation behaviors due to their self-interactions. The onset of this nonlinear oscillation can be investigated by linearizing… read more here.

DOI: 10.1103/physrevd.107.103034
Abstract: We explore the impact of small-scale flavor conversions of neutrinos, the so-called fast flavor conversions (FFCs), on the dynamical evolution and neutrino emission of core-collapse supernovae (CCSNe). In order to do that, we implement FFCs… read more here.

DOI: 10.1103/physrevlett.129.261101
Abstract: Despite the theoretical indication that fast neutrino-flavor conversion (FFC) ubiquitously occurs iin core-collapse supernovae and binary neutron star mergers, the lack of global simulations has been the greatest obstacle to study their astrophysical consequences. In… read more here.

DOI: 10.1103/physrevlett.130.211401
Abstract: One of the greatest uncertainties in any modeling of inner engine of core-collapse supernova (CCSN) is neutrino flavor conversions driven by neutrino self-interactions. We carry out large-scale numerical simulations of multi-energy, multi-angle, three-flavor framework, and… read more here.
