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

I review my recent progress and develop a geometrical approach in the quantum with light
as a guide, from the vector potential in classical physics, revealing that topological …

Half-quantized Hall conductance is characteristic of quantum systems with the parity
anomaly. Here, we investigate topological and transport properties of a class of parity …

In this paper we propose that quantized and nearly half-quantized intrinsic anomalous Hall
effect can be induced by in-plane external magnetic field through the Zeeman coupling in …

Two-dimensional topological semimetals are typically characterized by the vorticity of
gapless points, and can be classified according to the band representations. However, the …

Zigzag nanoribbons hosting the Haldane Chern insulator model are considered. In this
context, a reentrant topological phase, characterized by the emergence of quasi zero …

Condensed matter realization of a single Dirac cone of fermions in two dimensions is a long-
standing issue. Here we report the discovery of a single gapless Dirac cone of half …

The Wilson fermion (WF) is a fundamental particle in the theory of quantum
chromodynamics. Theoretical calculations have shown that the WF with a half skyrmion …

We predict a half-quantized mirror Hall effect induced by mirror symmetry in strong
topological insulator films. These films are known to host a pair of gapless Dirac cones in the …

Two-dimensional Dirac semimetals with a single massless Dirac cone exhibit a parity
anomaly. Usually, such a kind of anomalous topological semimetallic phase in real materials …
