Abstract

Neutrino oscillation is a significant physical process worthy of in-depth exploration. In this paper, we investigate the matter effect of massive neutrinos in a scalar-type ultra-light dark matter and calculate the neutrino oscillation probability using the quantum field theory method. The result reveals that the neutrino oscillation probability derived from the quantum field theory approach exhibits no additional time dependence, which marks the most significant distinction from the oscillation result obtained through the quantum mechanics method. Furthermore, we discuss predictions of the Juno experiment regarding neutrino oscillation behavior in scalar-type ultra-light dark matter. This study extends the understanding of the interaction between neutrinos and dark matter, which warrants further exploration.
