We propose to study atmospheric neutrino interactions with a unique event topology to distinguish neutrinos and anti-neutrinos using a liquid argon time projection chamber in an experiment such as DUNE. The detection of CC1P and CC0P events will allow to access neutrino oscillation physics complementary to accelerator based beam neutrinos. Our analysis shows that a sensitivity to the mass-ordering can be achieved with a significance close to 4{\sigma} and a CP violation sensitivity with more than 2{\sigma} with a data sample of 140 kt-yr of atmospheric neutrinos in the DUNE detector.
