Realization of low-energy Dirac fermions in (IrPt)Te superconductors
Binbin Fu, Changjiang Yi, Zhijun Wang +10
Superconducting and topological states are two distinct quantum states of matter. Superconductors with topologically nontrivial electronic states provide a platform to study the in…
Observation of bulk nodal lines in topological semimetal ZrSiS
Binbin Fu, Changjiang Yi, Tiantian Zhang +13
ZrSiS is the most intensively studied topological nodal-line semimetal candidate, which is proposed to host multiple nodal lines in its bulk electronic structure. However, previous…
Observation of Open-Orbit Fermi Surface Topology in Extremely Large Magnetoresistance Semimetal MoAs
R. Lou, Y. F. Xu, L. -X. Zhao +14
While recent advances in band theory and sample growth have expanded the series of extremely large magnetoresistance (XMR) semimetals in transition metal dipnictides (…
Three-component fermions with surface Fermi arcs in topological semimetal tungsten carbide
J. -Z. Ma, J. -B. He, Y. -F. Xu +19
Topological Dirac and Weyl semimetals not only host quasiparticles analogous to the elementary fermionic particles in high-energy physics, but also have nontrivial band topology ma…
Observation of oscillatory relaxation in the Sn-terminated surface of epitaxial rock-salt SnSe topological crystalline insulator
Wencan Jin, Suresh Vishwanath, Jianpeng Liu +20
Topological crystalline insulators have been recently predicted and observed in rock-salt structure SnSe thin films. Previous studies have suggested that the Se-terminate…
FeTeSe monolayer films: towards the realization of high-temperature connate topological superconductivity
Xun Shi, Zhiqing Han, Pierre Richard +7
We performed angle-resolved photoemission spectroscopy studies on a series of FeTeSe monolayer films grown on SrTiO. The superconductivity of the films is robus…
