Weyl and Dirac semimetals are three-dimensional phases of matter with gapless electronic
excitations that are protected by topology and symmetry. As three-dimensional analogs of …

Topological semimetals (TSMs) are characterized by bulk band crossings in their electronic
structures, which are expected to give rise to gapless electronic excitations and topological …

The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

Topological materials have become the focus of intense research in recent years, since they
exhibit fundamentally new physical phenomena with potential applications for novel devices …

The anomalous Hall effect (AHE) is one of the most fundamental phenomena in physics. In
the highly conductive regime, ferromagnetic metals have been the focus of past research …

Topological insulators and topological semimetals are both new classes of quantum
materials, which are characterized by surface states induced by the topology of the bulk …

A four-band terahertz tunable narrow-band perfect absorber based on a bulk Dirac semi-
metallic (BDS) metamaterial with a microstructure is designed. The three-layer structure of …

With the development of science and technology, intermediate infrared technology has
gained more and more attention in recent years. In the research described in this paper, a …

In a Dirac semimetal, each Dirac node is resolved into two Weyl nodes with opposite
“handedness” or chirality. The two chiral populations do not mix. However, in parallel electric …

Abstract Three-dimensional (3D) topologicalWeyl semimetals (TWSs) represent a state of
quantum matter with unusual electronic structures that resemble both a '3D graphene'and a …
