Pursuing topological phases in natural and artificial materials is one of the central topics in
modern physical science and engineering. In classical magnetic systems, spin waves (or …

Recently, topolectrical circuits (TECs) boom in studying the topological states of matter. The
resemblance between circuit Laplacians and tight-binding models in condensed matter …

Dimensionality plays a fundamental role in the classification of novel phases and their
responses. In generic lattices of 2D and beyond, however, we found that non-Hermitian …

We highlight a general theory to engineer arbitrary Hermitian tight-binding lattice models in
electrical LC circuits, where the lattice sites are replaced by the electrical nodes, connected …

Motivated by the recent experimental realizations of hyperbolic lattices in circuit quantum
electrodynamics and the research interest in the non-Euclidean generalization of topological …

Chiral edge states are highly sought after as paradigmatic topological states relevant to both
quantum information processing and dissipationless electron transport. Using …

We construct an electrical circuit to realize a modified Haldane lattice exhibiting the
phenomenon of antichiral edge states. The circuit consists of a network of inductors and …

Quadrupole topological insulators are a new class of topological insulators with quantized
quadrupole moments, which support protected gapless corner states. The experimental …

That disorder can induce nontrivial topology is a surprising discovery in topological physics.
As a typical example, Chern topological Anderson insulators (TAIs) have been realized in …

It is commonly believed that topologically nontrivial one-dimensional systems support edge
states rather than bulk states at zero energy. In this work, we find an unanticipated case of …
