Neutrino masses and mixing driven by randomness

Strong localisation via the so-called Anderson localisation is possible over different kinds of mass chains in theory space. This localisation can be used to generate tiny neutrino masses and mixing angles.
We show that in the limit of strong disorder, these models predict hierarchial neutrino masses and anarchical mixing angles. This is true for all geometries which can be local, non-local or mixed. On the other hand, if one considers weak disorder scenarios, localisation in mixing angles can also be obtained for certain models centered around the present experimental values. These models can serve new models to explain neutrino mixing patterns.
