These resonances may result in dramatic neutrino flavor transformation. Compact object merger disks are an example of an environment where electron antineutrinos outnumber neutrinos. We study MNR resonances in several such disk configurations and find two qualitatively different types of matter-neutrino resonances: a standard MNR and a symmetric MNR. We examine the transformation that occurs in each type of resonance and explore the consequences for nucleosynthesis.}, number={4}, journal={PHYSICAL REVIEW D}, author={Malkus, A. and McLaughlin, G.

Because accretion disks produce large quantities of neutrinos, they may be home to interesting neutrino oscillation as well. We model accretion disks associated with stellar collapse for the sake of understanding neutrino oscillations. We find that the neutrino oscillations include phenomena seen in the protoneutron star setting as well as phenomena not seen elsewhere.}, journal={NUINT12: 8TH INTERNATIONAL WORKSHOP ON NEUTRINO-NUCLEUS INTERACTIONS IN THE FEW-GEV REGION}, author={Malkus, A. and Kneller, J.

Discs that form from the end of life of rapidly rotating massive stars as well as discs that form from mergers will produce large numbers of neutrinos.

These disksproduce large numbers of neutrinos and antineutrinos of electron flavor that can influence energeticsand nucleosynthesis. Neutrinos are produced in sufficient numbers that, after they are emitted, theycan undergo flavor transformation facilitated by the neutrino self interaction. We show that someof the neutrino flavor transformation phenomenology for accretion disks is similar to that of thesupernova case, but also, we find the disk geometry lends itself to different transformation behaviors.These transformations strongly influence the nucleosynthetic outcome of disk winds.}, number={8}, journal={PHYSICAL REVIEW D}, publisher={American Physical Society (APS)}, author={Malkus, A. and Kneller, J.
