In all experimentally observed Weyl semimetals so far, the Weyl points always appear in pairs in the momentum space. Here, the authors report one unpaired Weyl point without surface Fermi arc emerging at the center of the Brillouin zone, which is sur

Local inversion symmetry breaking in centrosymmetric materials can lead to large spin polarization of the electronic band structure in separate sectors of the unit cell. Here, the authors reveal such hidden spin polarisation in ZrSiTe using spin and

Functional behaviour can emerge in materials in which magnetic order is determined by the interplay of localised and itinerant magnetic interactions. Here the authors tune such magnetic order in a photovoltaic perovskite by tuning the electronic carr

Weyl semimetals exhibit exotic properties owing to the presence of Weyl fermions. Here, Xu et al. show that tantalum phosphide is an ideal platform for studying the transport properties of these particles because its low-energy properties are dominat

Collective modes are responsible for the emergence of novel quantum phases in topological materials. In the quasi-one dimensional (1D) Weyl semimetal $(\mathrm{TaSe}_4)_2\mathrm{I}$ , a charge density wave (CDW) opens band gaps at the Weyl points, th

Constrained by the Nielsen-Ninomiya no-go theorem, in all so-far experimentally determined Weyl semimetals (WSMs) the Weyl points (WPs) always appear in pairs in the momentum space with no exception. As a consequence, Fermi arcs occur on surfaces whi

The recently discovered type-II Weyl points appear at the boundary between electron and hole pockets. Type-II Weyl semimetals that host such points are predicted to exhibit a new type of chiral anomaly and possess thermodynamic properties very differ

We investigate the evolution of both the occupied and unoccupied electronic structure in representative compounds of the infinitely adaptive superlattice series (Sb-2)(m)-Sb2Te3 (m = 0-3) by means of angle-resolved photoemission spectroscopy and time

Bulk Rashba systems BiTeX (X = I, Br, Cl) are emerging as important candidates for developing spintronics devices because of the coexistence of spin-split bulk and surface states, along with the ambipolar character of the surface charge carriers. The
