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 …

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 …

Topological quantum chemistry and symmetry-based indicators have facilitated large-scale
searches for materials with topological properties at the Fermi energy (EF). We report the …

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 …

Since the discovery of topological insulators and semimetals, there has been much research
into predicting and experimentally discovering distinct classes of these materials, in which …

In recent years, the notion of'Quantum Materials' has emerged as a powerful unifying
concept across diverse fields of science and engineering, from condensed-matter and …

Angle-resolved photoemission spectroscopy (ARPES)—an experimental technique based
on the photoelectric effect—is arguably the most powerful method for probing the electronic …

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 …

The physical description of all materials is rooted in quantum mechanics, which describes
how atoms bond and electrons interact at a fundamental level. Although these quantum …
