Charge-density wave transition in magnetic topological semimetal EuAl
R. Yang, C. C. Le, P. Zhu +5
The interplay among topology, charge-density wave (CDW), and magnetism can give rise to a plethora of exotic quantum phenomena. Recently, a group of magnetic topological semimetals…
A density-wave-like transition in the polycrystalline V3Sb2 sample with bilayer kagome lattice
N. N. Wang, Y. H. Gu, M. A. McGuire +13
Recently, transition-metal-based kagome metals have aroused much research interest as a novel platform to explore exotic topological quantum phenomena. Here we report on the synthe…
Observation of topological transition in high-T superconductor FeTeSe/SrTiO(001) monolayers
X. -L. Peng, Y. Li, X. -X. Wu +12
Superconductors with topological surface or edge states have been intensively explored for the prospect of realizing Majorana bound states, which obey non-Abelian statistics and ar…
Observation of high-Tc superconductivity in rectangular FeSe/STO(110) monolayer
P. Zhang, X. -L. Peng, T. Qian +12
It is well known that superconductivity in Fe-based materials is favoured under tetragonal symmetry, whereas competing orders such as spin-density-wave (SDW) and nematic orders eme…
Identification of prototypical Brinkman-Rice Mott physics in a class of iron chalcogenides superconductors
X. H. Niu, S. D. Chen, J. Jiang +17
The 122 series of iron-chalcogenide superconductors, for example KFeSe, only possesses electron Fermi pockets. Their distinctive electronic structure challe…

Single-layer FeSe film on SrTiO3(001) was recently found to be the champion of interfacial superconducting systems, with a much enhanced superconductivity than the bulk iron-based…
Observation of a Robust Zero-energy Bound State in Iron-based Superconductor Fe(Te,Se)
J. -X. Yin, Zheng Wu, J. -H. Wang +14
A robust zero-energy bound state (ZBS) in a superconductor, such as a Majorana or Andreev bound state, is often a consequence of non-trivial topological or symmetry related propert…
Enhanced superconductivity and evidence for novel pairing in single-layer FeSe on SrTiO3 thin film under large tensile strain
