As all observable effects of mixed quantum states, the coherence of neutrino oscillation is expected to be lost at some stage. Up to now, due to its unique property, observed neutrinos can either be classified to be in full coherence or full decoherence. However, as the precision of neutrino oscillation experiments increases, a fully coherent description would become insufficient at some...

The neutrino research program in the coming decades will require improved precision. A major source of uncertainty is the interaction of neutrinos with nuclei that serve as a target of many such experiments.

As experiments searching for neutrinoless double beta decay are in the planning phase of a next generation with hopes to completely probe the inverted mass hierarchy, the need for reliable nuclear matrix elements, which govern the rate of this decay, is stronger than ever.

Determinations of the effective Majorana mass from the neutrinoless double beta decay half-life depend on precise calculations of nuclear matrix elements (NMEs) of decay operators. These NMEs have a leading two-body component given by long-ranged (neutrino exchange), medium-ranged (pion exchange), and short-ranged (contact) contributions. Three-nucleon operators are, in most cases, not...
Neutrino flavor is expected to undergo fast and large oscillations due to collective effects in neutrino-dense environments, where neutrino-neutrino interactions are at play. While a quantum kinetics treatment is known to predict a smaller effect from non-forward scattering in such interactions compared to forward scattering (i.e., flavor swaps), this hierarchy has not yet been clearly...
