Time- and Space-Varying Neutrino Mass Matrix from Soft Topological Defects

Understand

We study the formation and evolution of topological defects that arise in the post-recombination phase transition predicted by the gravitational neutrino mass model in [Dvali, Funcke, Phys.

• D 93, 113002 (2016)].
• In the transition, global skyrmions, monopoles, strings, and domain walls form due to the spontaneous breaking of the neutrino flavor symmetry.
