The symmetry-indicators provide valuable information about the topological properties of band structures in real materials. For inversion-symmetric, non-magnetic materials, the pattern of parity eigenvalues of various Kramers-degenerate bands at the time-reversal-invariant momentum points are generally analyzed with the combination of strong Z4, and weak Z2 indices. Can the symmetry indicators identify the tunneling configurations of SU(2) Berry’s connections or the threedimensional, winding…
