摘要：

We address the role of short-range interactions for spinless fermions in the hyperhoneycomb lattice, a three-dimensional (3D) structure where all sites have a planar trigonal connectivity. For weak interactions, the system is a node-line semimetal. In the presence of strong interactions, we show that the system can be unstable to a 3D quantum anomalous Hall phase with loop currents that break time-reversal symmetry, as in the Haldane model. We find that the low-energy excitations of this state areWeyl fermions connected by surface Fermi arcs. We show that the 3D anomalous Hall conductivity is e(2)/(root 3ah), with a the lattice constant.
