Carbon has numerous one-dimensional (1D), two-dimensional (2D), and three-dimensional
(3D) allotropic structures. The study of carbon materials has long been a major focus of …

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 …

In topological semimetals, the valance band and conduction band meet at zero-dimensional
nodal points or one-dimensional nodal rings, which are protected by band topology and …

Abstract Three-dimensional Weyl and Dirac nodal points have attracted widespread interest
across multiple disciplines and in many platforms but allow for few structural variations. In …

In topological semimetals such as Weyl, Dirac, and nodal-line semimetals, the band gap
closes at points or along lines in k space which are not necessarily located at high-symmetry …

Based on first-principles calculations and effective model analysis, a Dirac nodal-net
semimetal state is recognized in AlB 2-type TiB 2 and ZrB 2 when spin-orbit coupling (SOC) …

Fermions with hourglass dispersions have been hotly studied in a nonmagnetic system
currently. However, magnetic ones have been rarely discussed because of the scarcity of …

Spin-gapless semimetals (SGSMs), which generate 100% spin polarization, are viewed as
promising semi-half-metals in spintronics with high speed and low consumption. We …

Nodal-chain fermions, which are novel topological states of matter, have been hotly
discussed in the field of nonmagnetic materials. Here, by using first-principles calculations …

We construct a generic two-band model which can describe topological semimetals with
multiple closed nodal loops. All the existing multi-nodal-loop semimetals, including the …
