Motivated by the topologically insulating circuit of capacitors and inductors proposed and tested by Jia et al. [arXiv:1309.0878], we present a related circuit with fewer elements per site. The normal mode frequency matrix of our circuit is unitarily equivalent to the hopping matrix of a quantum spin Hall insulator, and we identify perturbations that do not backscatter the circuit's edge modes. The idea behind these models is generalized, providing a platform to simulate tunable and locally…

Simulating quantum spin Hall effect in the topological Lieb lattice of a linear circuit network
Inspired by the topological insulator circuit experimentally proposed by Jia Ningyuan et al. [Phys. Rev. X 5, 021031 (2015)], we theoretically realize the topological Lieb lattice, a line-centered

Alternating current (ac) circuits can have electromagnetic edge modes protected by symmetries, analogous to topological band insulators or semimetals. How to make such a topological circuit? This
Topological Anderson insulator in electric circuits
In this paper, we investigate the realization of topological Anderson insulators in electric circuits. A disordered Haldane model is constructed through electric circuit networks composed of
Topological Zak phase in strongly coupled LC circuits
We show the emergence of topological Bogoliubov bosonic excitations in the relatively strong coupling limit of an LC (inductance-capacitance) one-dimensional quantum circuit. This dimerized chain
Topological Nodal States in Circuit Lattice
A scheme to realize topological nodal states with a three-dimensional periodic inductor-capacitor (LC) circuit lattice, where the topological nodsal line state and Weyl state can be achieved by tuning the parameters of inductors and capacitors.
Observation of corner states in second-order topological electric circuits
Recently, the topological states in electric circuits have attracted a great deal of attention, and they have formed the basis of the field of so-called topoelectrical circuits. We realize a
4D spinless topological insulator in a periodic electric circuit
It is argued that, because of its symmetry properties, the 4D spinless topological insulator is particularly well suited for implementation in these synthetic systems.
Observation of Antichiral Edge States in a Circuit Lattice
We constructed an electrical circuit to realize a modified Haldane lattice exhibiting the unusual phenomenon of antichiral edge states. The circuit consists of a network of inductors and capacitors
Topologically Protected Edge State in Two-Dimensional Su–Schrieffer–Heeger Circuit
This work design and experimentally demonstrate a topologically nontrivial band structure and the associated topologically protected edge states in an RF circuit, which is composed of a collection of grounded capacitors connected by alternating inductors in the x and y directions, in analogy to the Su–Schrieffer–Heeger model.

Bound states in the continuum (BICs) have received increasing attention from researchers because of their potential applications in photonic crystal fibers, as well as in lasing, sensing, and surface


Topological Insulators and Topological Superconductors
This graduate-level textbook is the first pedagogical synthesis of the field of topological insulators and superconductors, one of the most exciting areas of research in condensed matter physics.
When is a quantum measurement
The measurement of a quantum system is not consummated until irreversible processes have destroyed all phase coherence between different possible outcomes of that measurement. It is inconsistent to
We study the relation between the number of firms and market power in experimental oligopolies. Price competition under decreasing returns involves a wide interval of pure strategy equilibrium
