Drumhead surface states that link together loops of nodal lines arise in Dirac nodal-line semimetals as a consequence of the topologically non-trivial band crossings. We used low-temperature scanning tunneling microscopy and Fourier-transformed scanning tunneling spectroscopy to investigate the quasiparticle interference (QPI) properties of ZrSiTe. Our results show two scattering signals across the drumhead state resolving the energy-momentum relationship through the occupied and unoccupied…

Experimental observation of drumhead surface states in SrAs3
TLDR
The observation of a topological nodal-loop (TNL) in SrAs3, whereas CaAs3 exhibits a topologically trivial state is reported, and magneto-transport and magnetization data clearly suggest the presence (absence) of surface states in Sr as3 (CaAs3).
Observation of Effective Pseudospin Scattering in ZrSiS.
TLDR
This work uses Fourier transform scanning tunneling spectroscopy at 4.5 K to resolve quasiparticle interference (QPI) patterns at single defect centers on the surface of the line nodal semimetal zirconium silicon sulfide (ZrSiS) and finds that certain scatterers can introduce energy-dependent nonpreservation of pseudospin, giving rise to effective scattering between states with opposite pseudospIn deep inside valence and conduction bands.
Discovery of topological Weyl fermion lines and drumhead surface states in a room temperature magnet
TLDR
This study uses photoemission spectroscopy and quantum transport to elucidate the topology of the room temperature magnet Co2MnGa, and quantitatively account for the giant anomalous Hall response observed in this magnet.
Quasiparticle interference and nonsymmorphic effect on a floating band surface state of ZrSiSe
TLDR
It is found that the half-missing Umklapp process is derived from the glide mirror symmetry, thus identifying a non-symmorphic effect on quasiparticle interferences, and may pave a way towards potential new applications of nanoelectronics.
Transport evidence of 3D topological nodal-line semimetal phase in ZrSiS
Topological nodal-line semimetal is a new emerging material, which is viewed as a three-dimensional (3D) analog of graphene with the conduction and valence bands crossing at Dirac nodes, resulting in
Thermoelectric quantum oscillations in ZrSiS
TLDR
The study of the thermoelectric power of single-crystalline ZrSiS that is believed to be a topological nodal-line semimetal is reported, and the additional Berry phase predicted theoretically for materials with non-trivial topology is shown.
Weyl semimetal phase in the non-centrosymmetric compound TaAs
Experiments show that TaAs is a three-dimensional topological Weyl semimetal. Three-dimensional (3D) topologicalWeyl semimetals (TWSs) represent a state of quantum matter with unusual electronic
Large nonsaturating magnetoresistance and signature of nondegenerate Dirac nodes in ZrSiS
TLDR
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.
Similar ultrafast dynamics of several dissimilar Dirac and Weyl semimetals
Recent years have seen the rapid discovery of solids whose low-energy electrons have a massless, linear dispersion, such as Weyl, line-node, and Dirac semimetals. The remarkable optical properties
Unconventional mass enhancement around the Dirac nodal loop in ZrSiS
The topological properties of fermions arise from their low-energy Dirac-like band dispersion and associated chirality. Initially confined to points, extensions of the Dirac dispersion to lines, and
