Distorted Neutrino Oscillations From Ultralight Scalar Dark Matter
  Cold, ultralight ($\ll$ eV) bosonic dark matter with a misalignment abundance
can induce temporal variation in the masses and couplings of Standard Model
particles. We find that fast variations in neutrino oscillation parameters can
lead to significantly distorted neutrino oscillations (DiNOs) and yield
striking signatures at long baseline experiments. We study several
representative observables to demonstrate this effect and find that current and
future experiments including DUNE and JUNO are sensitive to a wide range of
viable scalar parameters over many decades in mass reach.
