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 …

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 …

The emerging class of topological materials provides a platform to engineer exotic electronic
structures for a variety of applications. As complex band structures and Fermi surfaces can …

Principles that predict reactions or properties of materials define the discipline of chemistry.
In this work, we derive chemical rules, based on atomic distances and chemical bond …

Dirac semimetals, which host Dirac fermions and represent a new state of quantum matter,
have been studied intensively in condensed-matter physics. The exploration of new …

We report an experimental study of the magnetic order and electronic structure and transport
of the layered pnictide EuMnSb 2, performed using neutron diffraction, angle-resolved …

Unconventional features of relativistic Dirac/Weyl quasiparticles in topological materials are
most evidently manifested in the two-dimensional quantum Hall effect (QHE), whose variety …

Due to the great application potential of the efficient interconversion between heat and
electricity, thermoelectric materials have long been the research focal points in condensed …

Dirac fermions, particles with zero rest mass, are observed in topological materials and are
believed to play a key role in the exotic phenomena in fundamental science and the …

Nonsymmorphic symmetries protect Dirac line nodes in square-net materials. This
phenomenon has been most prominently observed in ZrSiS. Here, we systematically study …
