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 …

We review recent theoretical progress in the understanding and prediction of novel
topological semimetals. Topological semimetals define a class of gapless electronic phases …

Discoveries of topological states and topological materials have reshaped our
understanding of physics and materials over the past 15 years. First-principles calculations …

Recent discoveries of topological phases realized in electronic states in solids have
revealed an important role of topology, which ubiquitously appears in various materials in …

Abstract Three-dimensional (3D) artificial metacrystals host rich topological phases, such as
Weyl points, nodal rings, and 3D photonic topological insulators. These topological states …

Based on first-principles calculations and analysis of crystal symmetries, we propose a kind
of hourglasslike nodal net (HNN) semimetal in centrosymmetric Ag 2 BiO 3 that is …

The electronic spectra of altermagnets are a fertile ground for non-trivial topology due to the
unique interplay between time-reversal and crystalline symmetries. This is reflected in the …

Materials carrying topological surface states (TSS) provide a fascinating platform for the
hydrogen evolution reaction (HER). Based on systematic first-principles calculations for A 3 …

Using density functional theory (DFT) calculations with the screened hybrid functional of
Heyd, Scuseria, and Ernzerhof (HSE06), we study the effects of hydrostatic pressure on the …

In some kind of three-dimensional higher-order topological insulators, bulk and surface
electronic states are gapped, while there appear gapless hinge states protected by spatial …
