Three-dimensional (3D) topological semimetals represent a new class of topological
matters. The study of this family of materials has been at the frontiers of condensed matter …

Whereas the discovery of Dirac-and Weyl-type excitations in electronic systems is a major
breakthrough in recent condensed matter physics, finding appropriate materials for …

We report angle-resolved photoemission experiments resolving the distinct electronic
structure of the inequivalent top and bottom (001) surfaces of WT e 2. On both surfaces, we …

Among all Fe-based superconductors, FeSe has the simplest composition and crystal
structure, with only the most basic structural unit, the FeSe layer. Due to the ease of …

The discovery of non-magnetic extreme magnetoresistance (XMR) materials has induced
great interest because the XMR phenomenon challenges our understanding of how a …

The discovery of a topological nodal-line (TNL) semimetal phase in ZrSiS has invigorated
the study of other members of this family. Here, we present a comparative electronic …

By combining angle-resolved photoemission spectroscopy and quantum oscillation
measurements, we performed a comprehensive investigation on the electronic structure of …

A notable phenomenon in topological semimetals is the violation of Kohler's rule, which
dictates that the magnetoresistance MR obeys a scaling behavior of MR= f (H/ρ 0), where …

We performed the angle dependent magnetoresistance (MR), Hall effect measurements, the
temperature dependent magneto-thermoelectric power (TEP) S (T) measurements, and the …

While pyrite-type PtBi 2 with a face-centered cubic structure has been predicted to be a three-
dimensional (3D) Dirac semimetal, experimental study of its physical properties remains …
