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 the recent, mainly theoretical, progress in the study of topological nodal line
semimetals in three dimensions. In these semimetals, the conduction and the valence bands …

Topological matter is known to exhibit unconventional surface states and anomalous
transport owing to unusual bulk electronic topology. In this study, we use photoemission …

In recent years, transition metal dichalcogenides (TMDs) have garnered great interest as
topological materials. In particular, monolayers of centrosymmetric β-phase TMDs have …

Materials harbouring exotic quasiparticles, such as massless Dirac and Weyl fermions, have
garnered much attention from physics and material science communities due to their …

Topologically protected fermionic quasiparticles appear in metals, where band
degeneracies occur at the Fermi level, dictated by the band structure topology. While in …

INTRODUCTION Condensed-matter systems have recently become a fertile ground for the
discovery of fermionic particles and phenomena predicted in high-energy physics; examples …

We have given a summary on our theoretical predictions of three kinds of topological
semimetals (TSMs), namely, Dirac semimetal (DSM), Weyl semimetal (WSM) and node-line …

Based on first-principles calculations and an effective Hamiltonian analysis, we
systematically investigate the electronic and topological properties of alkaline-earth …

We study the band topology and the associated linking structure of topological semimetals
with nodal lines carrying Z 2 monopole charges, which can be realized in three-dimensional …
