The unconventional magnetoresistance of ZrSiS single crystals is found unsaturated till the magnetic field of 53 T with the butterfly shaped angular dependence. Intense Shubnikov-de Haas oscillations resolve a bulk Dirac cone with a nontrivial Berry phase, where the Fermi surface area is 1.80*10^-3 A-2 and reaches the quantum limit before 20 T. Angle resolved photoemission spectroscopy measurement reveals an electronic state with the two-dimensional nature around the X point of Brillouin zone…

Crystal growth of Dirac semimetal ZrSiS with high magnetoresistance and mobility
TLDR
High quality single crystal ZrSiS as a theoretically predicted Dirac semimetal has been grown successfully using a vapor phase transport method and the transport and thermodynamic properties suggest a Fermi liquid behavior with two Fermani pockets at low temperatures.
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.

The topological quantum materials, including Dirac and Weyl semimetals, represent a new class of quantum materials with symmetry-protected band touching points. The essential properties of Dirac/Weyl
Nearly massless Dirac fermions and strong Zeeman splitting in the nodal-line semimetal ZrSiS probed by de Haas–van Alphen quantum oscillations
Topological semimetals harbor relativistic fermions featuring light effective mass, high mobility, and a nontrivial Berry phase. Quantum oscillations are an effective means to probe the properties of
Evidence of Topological Nodal-Line Fermions in ZrSiSe and ZrSiTe.
TLDR
ZrSiSe and ZrSiTe single crystals can be thinned down to 2D atomic thin layers through microexfoliation, which offers the first platform to explore exotic properties of topological nodal-line fermions in low dimensions.
Crossing-line-node semimetals: General theory and application to rare-earth trihydrides
Multiple line nodes in energy-band gaps are found in semimetals preserving mirror-reflection symmetry. We classify possible configurations of multiple line nodes with crossing points (crossing line

Topological phases of matter have been among the most active research subjects in condensed matter physics. They can be broadly classified as two major classes. The first class of phases, including
Nodal-link semimetals
In topological semimetals, the valance band and conduction band meet at zero-dimensional nodal points or one-dimensional nodal rings, which are protected by band topology and symmetries. In this

Topological Dirac semimetals (TDSs) represent a new state of quantum matter recently discovered that offers a platform for realizing many exotic physical phenomena. A TDS is characterized by the
Nodal-knot semimetals
Topological nodal-line semimetals are characterized by one-dimensional lines of band crossing in the Brillouin zone. In contrast to nodal points, nodal lines can be in topologically nontrivial

Butterfly magnetoresistance, quasi-2D Dirac Fermi surface and topological phase transition in ZrSiS
TLDR
The observation of an unusual “butterfly”-shaped titanic angular magnetoresistance (AMR) in the nonmagnetic Dirac material, ZrSiS, which is found to be the most conducting sulfide known, with a 2-K resistivity as low as 48(4) nΩ⋅cm is reported.
Dirac cone protected by non-symmorphic symmetry and three-dimensional Dirac line node in ZrSiS
TLDR
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.
