Besides chiral edge states, the hallmark of quantum Hall insulators, antichiral edge states
can exhibit unidirectional transport behavior but in topological semimetals. Although such …

Despite a rapidly expanding inventory of possible crystalline Weyl semimetals, all of them
are constrained by the Nielsen-Ninomiya no-go theorem, namely, that left-and right-handed …

Carbon has numerous one-dimensional (1D), two-dimensional (2D), and three-dimensional
(3D) allotropic structures. The study of carbon materials has long been a major focus of …

In the past few decades, the discovery of topological matter states has ushered in a new era
in topological physics, providing a robust framework for strategically controlling the transport …

Nodal-chain fermions, which are novel topological states of matter, have been hotly
discussed in the field of nonmagnetic materials. Here, by using first-principles calculations …

The recent development in topological photonics has revealed a variety of exotic
phenomena such as Weyl degeneracy. However, a Weyl nodal surface, a two-dimensional …

In recent years, topological photonics inspired by electric topological insulators has
promoted extensive research on robust electromagnetic (EM) wave manipulation and new …

In the past few years, the concept of topological matter has inspired considerable research
