Abstract

In this paper, I present a discussion on the length scale of collective neutrino oscillations. There is a popular myth in the field that the length scale of collective neutrino oscillation is related to the strength of self-interaction potential; this is a result of confusion between the length scale and time scale. As a consequence of this myth, it is believed that the convergence of numerical simulation of quantum kinetic equations requires a spatial resolution (radial bin size) that is equal to the inverse of the self-interaction potential. I try to debunk this myth in this paper.
