From ray to spray: augmenting amplitudes and taming fast oscillations in fully numerical neutrino codes
Abstract In this note we describe how to complement the neutrino evolution matrix calculated at a given energy and trajectory with additional information which allows to reliably extrapolate it to nearby energies or trajectories without repeating the full computation. Our method works for arbitrary...
