The authors observe the second-order corner states pinned to zero energy that is characterized by Z3 Berry phase in the platform of topolectrical circuits. They examine the topological robustness of the zero modes against both chiral-symmetry conserving and breaking disturbances by introducing extra capacitors within sublattices in electrical-circuit experiments.
