The “once-in-a-lifetime encounter” approach: Neutrino oscillations beyond the mean-field paradigm

Tuesday March 26, 2024
2:00 pm

 Presenter:  Anson Kost (UNM)
 Series:  Nuclear, Particle, Astroparticle and Cosmology (NUPAC) Seminars
 Abstract:  Currently, the standard approach to collective neutrino oscillations is the mean-field approach. However, its validity has been called into question, since it does not account for entanglement between neutrinos. I will present an alternative approach, in which neutrinos are represented as 2-level open quantum systems that interact with each other and can become entangled. Our approach is motivated by the idea that, in astrophysical environments, a pair of neutrinos will meet each other only once in their lifetimes ("ichi-go ichi-e"). Standard mean-field results, as well as results predicted by newer many-body models, emerge as limits of our model.
