Title: Topological circuits: topological phases in classical electrical circuits

Abstract:
The concept of topology has recently been introduced into the classical systems, such as photonics and acoustics, and various topological phases are discovered. Among the classical systems, electrical circuits are a promising platform to realize the remarkable topological phases because of the highly flexibility and controllability. In this talk, I will present our recent progress on topological circuits and introduce two kinds of topological phases in classical electrical circuits: the ideal type-II Weyl points and the quasicrystalline quadrupole topological insulators.
