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 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 …

This is an introductory review of the physics of topological quantum matter with cold atoms.
Topological quantum phases, originally discovered and investigated in condensed matter …

Flat-band materials such as the kagome metals or moiré superlattices are of intense current
interest. Flat bands can result from the electron motion on numerous (special) lattices and …

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 …

Spintronics aims to utilize the spin degree of freedom for information storage and computing
applications. One major issue is the generation and detection of spins via spin and charge …

In recent years, novel families of materials have been discovered and significant
improvements in classical thermoelectric materials have been made. Thermoelectric …

Cuprate superconductors have long been thought of as having strong electronic correlations
but negligible spin-orbit coupling. Using spin-and angle-resolved photoemission …

Samarium hexaboride (SmB6) is an example of a Kondo insulator, in which strong electron
correlations cause a band gap to open. SmB6 hosts both a bulk insulating state and a …

Strongly correlated systems present fundamental challenges, especially in materials in
which electronic correlations cause a strong increase of the effective mass of the charge …
