The MSW effect in the neutrino background

I will discuss the physics of coherent neutrino flavor conversion in the neutrino background. I will argue that the essence of the effect can be simply understood as an interference of many elementary amplitudes, at the level of undergraduate quantum mechanics. I will also review the recent mini-controversy in the field about the existence of a novel many-particle coherent effect. As time permits, applications of the formalism will be discussed.
