Neutrino Quantum Kinetics in the Early Universe

We study the quantum kinetic evolution of neutrinos in the early universe where the hot and dense conditions result in neutrino interactions with matter and other neutrinos and anti-neutrinos. Under these conditions, neutrino-neutrino interactions can cause non-linear evolution. In this poster we explore the neutrino quantum kinetic evolution in scenarios with a net neutrino lepton-number (asymmetry between the numbers of neutrinos and anti-neutrinos).
