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 …

Superconductivity has been observed in moiré systems such as twisted bilayer graphene,
which host flat, dispersionless electronic bands. In parallel, theory work has discovered that …

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 …

A central result in superconductivity is that flat bands, though dispersionless, can still host a
nonzero superfluid weight due to quantum geometry. We show that the derivation of the …

This review presents the state of the art in strain and ripple-induced effects on the electronic
and optical properties of graphene. It starts by providing the crystallographic description of …

Based on first-principles calculation and effective model analysis, we propose that the cubic
antiperovskite material Cu 3 PdN can host a three-dimensional (3D) topological node-line …

Graphene, a two-dimensional (2D) carbon sheet, acquires many of its amazing properties
from the Dirac point nature of its electronic structures with negligible spin-orbit coupling …

Based on the ab initio calculations, we show that MoTe 2, in its low-temperature
orthorhombic structure characterized by an x-ray diffraction study at 100 K, realizes 4 type-II …

Topological invariants built from the periodic Bloch functions characterize new phases of
matter, such as topological insulators and topological superconductors. The most important …

The last decade has witnessed great advancements in the science and engineering of
systems with unconventional band structures, seeded by studies of graphene and …
