Evolution of Electronic and Magnetic Properties in Topological Semimetal SmSbxTe2-x

The ZrSiS-type materials have attracted intensive attention due to the existence of various topological fermions. The magnetic version of the ZrSiS-type materials, LnSbTe (Ln = lanthanides), is an

Electronic Band Structure and Surface States in Dirac Semimetal LaAgSb2

LaAgSb2 is a Dirac semimetal showing charge density wave (CDW) order. Previous angle-resolved photoemission spectroscopy (ARPES) results suggest the existence of the Dirac-cone-like structure in the

Observation of gapless nodal-line states in NdSbTe

( Ln )-based systems in the nodal-line semimetals have been subjects of research investigations as grounds for studying the interplay of topology with possible magnetic ordering and electronic

Magnetic Topological Semimetal Phase with Electronic Correlation Enhancement in SmSbTe

The ZrSiS family of compounds hosts various exotic quantum phenomena due to the presence of both topological nonsymmorphic Dirac fermions and nodal‐line fermions. In this material family, the LnSbTe

Experimental discovery of Weyl semimetal TaAs

In 1929, H. Weyl proposed that the massless solution of the Dirac equation represents a pair of a new type of particles, the so-called Weyl fermions. However, their existence as a fundamental

Unusual magnetotransport from Si-square nets in topological semimetal HfSiS

The class of topological semimetals comprises a large pool of compounds. Together they provide a wide platform to realize exotic quasiparticles for example Dirac, nodal line Dirac and Weyl fermions.

Dirac cone protected by non-symmorphic symmetry and three-dimensional Dirac line node in ZrSiS

This work shows that the highly stable, non-toxic and earth-abundant material, ZrSiS, has an electronic band structure that hosts several Dirac cones that form a Fermi surface with a diamond-shaped line of Dirac nodes, making it a very promising candidate to study Dirac electrons, as well as the properties of lines ofDirac nodes.

Beyond Dirac and Weyl fermions: Unconventional quasiparticles in conventional crystals

The guiding principle of the classification is to find irreducible representations of the little group of lattice symmetries at high-symmetry points in the Brillouin zone for each of the 230 space groups (SGs), the dimension of which corresponds to the number of bands that meet at the high-Symmetry point.

Tunable Weyl and Dirac states in the nonsymmorphic compound CeSbTe

By establishing magnetic order in a square lattice compound, this work introduces the first magnetic “new fermion” and shows that it can realize a rich variety of different topological semimetal states in a single material, CeSbTe.

Large nonsaturating magnetoresistance and signature of nondegenerate Dirac nodes in ZrSiS

The magnetotransport study on ZrSiS crystal is presented, which represents a large family of materials (WHM with W = Zr, Hf; H = Si, Ge, Sn; M = O, S, Se, Te) with identical band topology.

Discovery of a Weyl fermion semimetal and topological Fermi arcs

The experimental discovery of a Weyl semimetal, tantalum arsenide (TaAs), using photoemission spectroscopy, which finds that Fermi arcs terminate on the Weyl fermion nodes, consistent with their topological character.
