Propagation of Semiclassical Wave Front Sets for Non-Self-Adjoint Matrix-Valued Pseudo-Differential Operators
Yuta Kawamura
We study the semiclassical wave front set of vector-valued microlocal solutions to the pseudo-differential system with a non-Hermitian matrix-valued symbol. The main result establi…

Spacetime evolution of lepton number densities and wave packet-like effects for neutrino flavor and chiral oscillations in quantum field theory
Apriadi Salim Adam, Nicholas J. Benoit, Yuta Kawamura +4
We present a formulation of lepton family numbers, based on quantum field theory, for neutrino oscillation phenomenology that can be applied to nonrelativistic and relativistic ene…

Determination of Majorana type-phases from the time evolution of lepton numbers
Nicholas J. Benoit, Yuta Kawamura, Saki Hamada +3
We have investigated an approach for determining the Majorana type-phases using the time evolution of lepton family numbers. We show how the second-order time derivative of the exp…
