Simulating neutrino oscillations on a multi-level quantum system

Neutrino oscillation is a well-established phenomenon explained by quantum field theory (QFT). In the standard model (SM) description, neutrinos are massless and weakly interacting particles. However, to explain the experimental results, it was established that neutrinos have mass and undergo mixing between different flavors. Neutrino oscillation, which implies that neutrinos can change from one flavor to another, is a consequence of the neutrino masses and lepton mixing. The observation of neutrino oscillation has opened a window for physics beyond the SM.
