A sterile neutrino with a novel density-dependent matter potential Vs resolves multiple oscillation anomalies when Vs is negative and mixing angles are small.
T2K and NOνA extract only a small fraction of the quantum information about δ_CP, with extraction efficiency particularly suppressed near maximal CP violation.
Model-agnostic treatment of neutrino cross-section ratios degrades CP-violation sensitivity in DUNE and T2HK by 3-4σ, but prospective νSCOPE data restores most of it.
Off-diagonal NSI parameters modify EOF, Concurrence and Negativity in neutrino oscillations, with largest effects at low energy and Negativity remaining dominant at higher energies while showing clear δ_CP dependence.
Simulations show that tau neutrino appearance at DUNE improves sensitivity to NSI parameters especially ε_μτ, hierarchy, CP violation, octant, NSI phases, and PMNS unitarity constraints.
Analysis of recent NOνA and T2K data under non-unitary mixing yields tighter 90% limits on non-unitary parameters than prior data and indicates that α10 could reduce the 1σ tension between experiments for normal hierarchy.
