Zero-energy corner states protected by generalized chiral symmetry in C 4 symmetric crystals

We investigated the corner-states characteristics of C _4 -symmetric higher-order topological crystalline insulators. By evaluating the charge polarization and fractional corner charge, we obtained the abundant topological properties for different intercell hoppings amplitudes and identified that th...
