Chiral topological insulating phases from three-dimensional nodal loop semimetals
We identify a topological Z index for three-dimensional chiral insulators with P ∗ T symmetry where two Hamiltonian terms define a nodal loop. Such systems may belong in the AIII or DIII symmetry class. The Z invariant is a winding number assigned to the nodal loop and has a correspondence to the ge...
