Fast flavor evolution in dense neutrino systems, as described in quantum field theory
R. F. Sawyer
Investigations of dense neutrino cloud evolution through quantum kinetic equations led to the possibility of ``fast flavor" (FF) processes. It is shown here that the usual quantum…
Neutrino-anti-neutrino instability in dense neutrino systems, with applications to the early universe and to supernovae
R. F. Sawyer
We exhibit a new instability that leads to "fast" coherent neutrino-antineutrino mixing in a dense neutrino cloud, arising from the standard four-Fermi interaction induced by Z exc…
Neutrino collective effects and sterile neutrino production in the early universe
R. F. Sawyer
Neutrino-neutrino interactions, as mediated by standard model Z exchange, can drastically enhance the Dodelson-Widrow mechanism for the production of sterile neutrinos in the regio…
Neutrino collective effects during their decoupling era in the early universe
Raymond F. Sawyer
There is an accepted approach to calculation of the neutrino flavor density-matrix in the halo of a supernova, in which neutrino amplitudes, not cross-sections, need to be followed…
Neutrino refractive effects during their decoupling era in the early universe
R. F. Sawyer
There is an accepted approach to calculation of the neutrino flavor density-matrix in the halo of a supernova, in which neutrino amplitudes, not cross-sections, need to be followed…
Quantum breaks in a model for the evolution of neutrinos during their decoupling era in the big bang
R. F. Sawyer
An active two-neutrino state's coupling to an intermediate scalar meson, and thence to a two-antineutrino state, is one idea for catalyzing transitions from active to sterile neutr…
