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 …

The discovery of the quantum spin Hall effect and topological insulators more than a decade
ago has revolutionized modern condensed matter physics. Today, the field of topological …

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 …

Motivated by recent experiments on Kondo insulators, we theoretically study quantum
oscillations from disorder-induced in-gap states in small-gap insulators. By solving a non …

Strange metals possess highly unconventional electrical properties, such as a linear-in-
temperature resistivity,,,,–, an inverse Hall angle that varies as temperature squared,–and a …

Time reversal symmetry (TRS) protects the metallic surface modes of topological insulators
(TIs). The transport signature of such surface states is a plateau that arrests the exponential …

Insulators occur in more than one guise; a recent finding was a class of topological
insulators, which host a conducting surface juxtaposed with an insulating bulk. Here, we …

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 …

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 …
