Higher-order topological electric circuits and topological corner resonance on the breathing kagome and pyrochlore lattices

Physical Review B, 2018
Electric circuits are known to realize topological quadrupole insulators. We explore electric circuits made of capacitors and inductors forming the breathing Kagome and pyrochlore lattices. They are known to possess three phases (trivial insulator, higher-order topological insulator and metallic phases) in the tight-binding model. The topological phase
