Geometric phases in neutrino oscillations with nonlinear refraction
Lucas Johns, George M. Fuller
Neutrinos propagating in dense astrophysical environments sustain nonlinear refractive effects due to neutrino-neutrino forward scattering. We study geometric phases in neutrino os…
An optimization-based approach to calculating neutrino flavor evolution
Eve Armstrong, Amol V. Patwardhan, Lucas Johns +3
We assess the utility of an optimization-based data assimilation (D.A.) technique for treating the problem of nonlinear neutrino flavor transformation in core collapse supernovae.…
Neutrino flavor transformation in the lepton-asymmetric universe
Lucas Johns, Mattia Mina, Vincenzo Cirigliano +2
We investigate neutrino flavor transformation in the early universe in the presence of a lepton asymmetry, focusing on a two-flavor system with 1 - 3 mixing parameters. We identify…
