SUMMARY:National Superconducting Cyclotron Laboratory Seminar
DESCRIPTION:
 Sherwood Richards, III, University of California, 
 Berkeley, will be speaking.\n
 \n
 The presentation 
 is titled "3D Simulations of the Neutrino 
 Fast Flavor Instability."\n
 \n
 Abstract: Neutrinos 
 transport energy, drive outflows, and 
 determine the ratio of electrons to protons 
 in the ejecta from neutron star mergers that 
 enriches the surrounding universe with heavy 
 elements. Only electron flavor neutrinos and 
 antineutrinos modify the composition of the ejecta 
 and thus directly affect the synthesis 
 of heavy elements. Instabilities that cause rapid 
 mixing of neutrino flavor are likely ubiquitous 
 in mergers, but are poorly understood 
 and are absent from global simulations. I will 
 present the first (local) three-dimensional 
 simulations of this instability using the new 
 open-source particle-in-cell neutrino quantum 
 kinetics code Emu. I will demonstrate that 
 the growth phase of the instability matches 
 theoretical predictions, describe abundances 
 of each neutrino species after the instability 
 saturates, and discuss the implications for 
 nucleosynthesis in neutron star mergers.\n\n
