Millimeter-sized MnBi 2 Te 4 single crystals are grown out of a Bi-Te flux and characterized
using magnetic, transport, scanning tunneling microscopy, and spectroscopy …

Topology and electron interactions are two central themes in modern condensed matter
physics. Here, we propose graphene-based systems where both the band topology and …

The interplay between symmetry and topology leads to a rich variety of electronic topological
phases, protecting states such as the topological insulators and Dirac semimetals. Previous …

Spin–orbit coupling (SOC) describes the relativistic interaction between the spin and
momentum degrees of freedom of electrons, and is central to the rich phenomena observed …

The quantum anomalous Hall (QAH) effect has attracted extensive attention due to time-
reversal symmetry broken by a staggered magnetic flux emerging from ferromagnetic …

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 …

Materials can harbour quantum many-body systems, most typically in the form of strongly
correlated electrons in solids, that lead to novel and remarkable functions thanks to …

Topological materials discovery has evolved at a rapid pace over the past 15 years following
the identification of the first nonmagnetic topological insulators (TIs), topological crystalline …

Semimetals are being explored for their unique advantages in low-energy high-speed
photodetection, although they suffer from serious drawbacks such as an intrinsically high …

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 …
