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 …

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 …

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 …

Weyl semimetal is the three-dimensional analog of graphene. According to quantum field
theory, the appearance of Weyl points near the Fermi level will cause novel transport …

The first-principles band theory paradigm has been a key player not only in the process of
discovering new classes of topologically interesting materials, but also for identifying salient …

Three-dimensional (3D) topological Dirac semimetals (TDSs) represent an unusual state of
quantum matter that can be viewed as “3D graphene.” In contrast to 2D Dirac fermions in …

Over the past decade, topological materials—in which the topology of electron bands in the
bulk material leads to robust, unconventional surface states and electromagnetism—have …

Topological electronic materials such as bismuth selenide, tantalum arsenide and sodium
bismuthide show unconventional linear response in the bulk, as well as anomalous gapless …
