Topological Type-II Nodal Line Semimetal and Dirac Semimetal State in Stable Kagome Compound Mg3Bi2.
TLDR
It is proposed that a stable Kagome compound Mg3Bi2 can host a type-II nodal line state with the protection of time reversal and spatial inversion symmetries and is expected to be a good candidate to investigate the exotic properties of both type- II NLS and 3D Dirac semimetal states.
Ideal fully spin-polarized type-II nodal line state in half-metals X2YZ4 (X=K, Cs, Rb, Y Cr, Cu, Z=Cl, F)
Lorentz-violating type-II nodal lines exhibit attracting physical properties and have been hot discussed currently. However, their investigations have been mostly limited in nonmagnetic system…
Type II Nodal line Semimetal
Recently, topological semimetals become hot topic in condensed matter physics, including Dirac semimetal, Weyl semimetal, and nodal line semimetal (NLSM). In this paper, a new type of node- line…
Quantum-limit Chern topological magnetism in TbMn6Sn6
TLDR
Scanning tunnelling microscopy is used to reveal a new topological kagome magnet with an intrinsic Chern quantum phase, which shows a distinct Landau fan structure with a large Chern gap, and the realization of a quantum-limit Chern phase in TbMn6Sn6 is point to.
Discovery of a Three-Dimensional Topological Dirac Semimetal, Na3Bi
TLDR
Na3Bi is established as a model system for 3D TDSs, which can serve as an ideal platform for the systematic study of quantum phase transitions between rich topological quantum states, and the robustness of 3D Dirac fermions in Na3Bi against in situ surface doping is demonstrated.
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.
Unusual competition of superconductivity and charge-density-wave state in a compressed topological kagome metal
TLDR
High-pressure electrical transport and magnetic susceptibility measurements to study CsV3Sb5 with the highest Tc of 2.7 K indicate an unusual competition between superconductivity and CDW state in pressurized kagome lattice.
Beyond Dirac and Weyl fermions: Unconventional quasiparticles in conventional crystals
TLDR
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.
Realization of a Type‐II Nodal‐Line Semimetal in Mg3Bi2
TLDR
The angle‐resolved photoemission spectroscopy measurements agree well with the first‐principles results below the Fermi level and thus strongly suggest Mg3Bi2 as an ideal material platform for studying the as‐yet unstudied properties of type‐II nodal‐line semimetals.
