Perturbative exponential expansion and matter neutrino oscillations
A. D. Supanitsky, J. C. D'Olivo, G. Medina-Tanco
We derive an analytical description of neutrino oscillations in matter based on the Magnus exponential representation of the time evolution operator. Our approach is valid in a wid…

Analytical description of the Day-Night neutrino asymmetry
A. D. Supanitsky, J. C. D'Olivo, G. A. Medina-Tanco
We present a new treatment of the Earth matter effects on the neutrino oscillations that is valid for an arbitrary density profile. When applied to the the study of the day-night e…
