Neutrino transport and flavor instabilities in a post-merger disk

Erick Urquilla, Swapnil Shankar, Debraj Kundu +6

Neutron star mergers are multimessenger sources whose dynamics and signals depend critically on neutrinos and their flavor transformations. We investigate whether fast and collisio…

Chaos in Inhomogeneous Neutrino Fast Flavor Instability

Erick Urquilla, Sherwood Richers

In dense neutrino gases, the neutrino-neutrino coherent forward scattering gives rise to a complex flavor oscillation phenomenon not fully incorporated in simulations of neutron st…

Neutrino flavor instabilities in neutron star mergers with moment transport: Slow, fast, and collisional modes

Julien Froustey, Francois Foucart, Christian Hall +5

Determining where, when, and how neutrino flavor oscillations must be included in large-scale simulations of hot and dense astrophysical environments is an enduring challenge that…

Impact of Neutrino Flavor Conversions on Neutron Star Merger Dynamics, Ejecta, Nucleosynthesis, and Multi-Messenger Signals

Yi Qiu, David Radice, Sherwood Richers +3

We present numerical relativity simulations of binary neutron star mergers incorporating neutrino flavor transformations triggered by fast flavor instability, quantum many-body eff…

Two-beam Multiparticle Many-body simulations of Inhomogeneous FFI

Zoha Laraib, Sherwood Richers

Neutrino flavor evolution in dense astrophysical environments is inherently nonlinear and sensitive to many-body (MB) quantum effects beyond the mean-field (MF) approximation. Exis…

Many-Body Simulations of the Fast Flavor Instability

Zoha Laraib, Sherwood Richers

The neutrino fast flavor instability dominates the evolution of neutrino flavor within the engines of core-collapse supernovae and neutron star mergers. However, theoretical models…
