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 …

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 …

Abstract Symmetry-broken three-dimensional (3D) topological Dirac semimetal systems with
strong spin-orbit coupling can host many exotic Hall-like phenomena and Weyl fermion …

For decades, borides have been primarily studied as crystallographic oddities. With such a
wide variety of structures (a quick survey of the Inorganic Crystal Structure Database counts …

Unveiling new topological phases of matter is one of the current objectives in condensed
matter physics. Recent experimental discoveries of Dirac and Weyl semimetals prompt the …

This article reviews recent theoretical and experimental work on a new class of topological
material—topological Kondo insulators, which develop through the interplay of strong …

In the Kondo insulator samarium hexaboride (SmB6), strong correlation and band
hybridization lead to an insulating gap and a diverging resistance at low temperature. The …

A topological insulator (TI) is an unusual quantum state in which the insulating bulk is
topologically distinct from vacuum, resulting in a unique metallic surface that is robust …

SmB6, a well-known Kondo insulator, exhibits a transport anomaly at low temperature. This
anomaly is usually attributed to states within the hybridization gap. Recent theoretical work …
