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 …

The realization of Dirac and Weyl physics in solids has made topological materials one of
the main focuses of condensed matter physics. Recently, the topic of topological nodal line …

Since the discovery of topological insulators and semimetals, there has been much research
into predicting and experimentally discovering distinct classes of these materials, in which …

A Dirac nodal-line semimetal phase, which represents a new quantum state of topological
materials, has been experimentally realized only in a few systems, including PbTaSe 2, PtSn …

Initiated by the discovery of topological insulators, topologically non-trivial materials have
attracted immense interest in the physics community in the past decade. One of the latest …

Topological Dirac semimetals (TDSs) represent a new state of quantum matter recently
discovered that offers a platform for realizing many exotic physical phenomena. A TDS is …

Topological semimetals represent a new class of quantum materials hosting Dirac/Weyl
fermions. The essential properties of topological fermions can be revealed by quantum …

Many materials crystallize in structure types that feature a square net of atoms. While these
compounds can exhibit many different properties, some members of this family are …

We have performed angle-resolved photoemission spectroscopy on HfSiS, which has been
predicted to be a topological line-node semimetal with square Si lattice. We found a quasi …

Recent interest in topological semimetals has led to the proposal of many new topological
phases that can be realized in real materials. Next to Dirac and Weyl systems, these include …
