  • Dirac semimetals possess an electronic dispersion relation which is linear in three dimensions, making them three-dimensional analogues of graphene. Here, the authors report large negative magnetoresistance in single-crystal Cd3As2nanowires, evidencing a sought-after chiral anomaly effect.

  • Dirac semimetals are a three-dimensional analogue of graphene that can support massless Dirac fermions in their bulk and Fermi-arc surface states. Here, the authors observe Aharonov–Bohm oscillations in transport measurements on Cd3As2nanowires, revealing these exotic surface states.

  • Superconductivity through the topological surface states of a Dirac semimetal remains elusive. Here, the authors fabricate a Nb-Cd3As2-Nb Josephson junction and observe supercurrent oscillations from surface Fermi arcs of Cd3As2

  • The non-Hermitian skin effect, or localization of eigenstates at the boundary of a non-Hermitian system, has been intensively studied. Chu et al. observe a large and wide edge supercurrent in the Dirac semimetal Cd3As2-based Josephson junctions, which is consistent with the non-Hermitian skin effect.
