The topological insulator (TI) is a new phase of matter that exhibits quantum-Hall-like properties, even in the absence of an external magnetic field. Understanding and characterizing unique properties of these materials can lead to many novel applications, such as current induced magnetization or extremely robust quantum memory bits.

The detection of topological phases of matter has become a central issue in recent years. Conventionally, the realization of a specific topological phase in condensed matter physics relies on probing the underlying surface band dispersion or quantum transport signature of a real material, which may be imperfect or even absent.

Topological Anderson Insulator in Disordered Photonic Crystals Gui-Geng Liu, Yihao Yang, Xin Ren, Haoran Xue, Xiao Lin, Yuan-Hang Hu, Hong-xiang Sun, Bo Peng, Peiheng Zhou, Yidong Chong, and Baile Zhang The story of the topological insulator began with the discovery of the quantum spin Hall effect (QSH) in 1980. QSH was the first example of a quantum state with spontaneously broken symmetry, meaning it comprises of a symmetric probability distribution where any pair of outcomes has the same probability of occurring. A quadrupole topological insulator, being one higher-order topological insulator with nontrivial quadrupole quantization, has been intensely investigated very recently. However, the tight-binding model proposed for such emergent topological insulators demands both positive and negative hopping coefficients, which imposes an obstacle in practical realizations. Here, we introduce a feasible This review briefly describes the development of synthetic topological insulator materials in the application of advanced electronic devices. As a new class of quantum matter, topological insulators with insulating bulk and conducting surface states have attracted attention in more and more research fields other than condensed matter physics due to their intrinsic physical properties, which We review 3D topological insulators (as introduced in Sec. II B) and their response when irradiated with light.
