The half-quantized Hall conductance is characteristic of quantum systems withparity anomaly. Here we investigate topological and transport properties of aclass of parity anomalous semimetals, in which massive Dirac fermions coexistwith massless Dirac fermions in momentum space or real space, and uncovered adistinct bulk-edge correspondence that the half-quantized Hall effect isrealized via the bulk massless Dirac fermions while the nontrivial Berrycurvature is provided by the massive Dirac fermions. The spatial distributionof the edge current decays away from the boundary in a power law instead of anexponential law in integer quantum Hall effect. We further address physicalrelevance of parity anomalous semimetal to three-dimensional semi-magnetictopological insulators and two-dimensional photonic crystals.
