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…
Effect of Zn doping on the antiferromagnetism in kagome CuZn(OH)FBr
Zili Feng, Yuan Wei, Ran Liu +10
Barlowite Cu(OH)FBr shows three-dimensional (3D) long-range antiferromagnetism, which is fully suppressed in CuZn(OH)FBr with a kagome quantum spin liquid ground st…
Experimental observation of node-line-like surface states in LaBi
Baojie Feng, Jin Cao, Meng Yang +10
In a Dirac nodal line semimetal, the bulk conduction and valence bands touch at extended lines in the Brillouin zone. To date, most of the theoretically predicted and experimentall…
Pressure-induced Superconductivity in the Three-component Fermion Topological Semimetal Molybdenum Phosphide
Zhenhua Chi, Xuliang Chen, Chao An +15
Topological semimetal, a novel state of quantum matter hosting exotic emergent quantum phenomena dictated by the non-trivial band topology, has emerged as a new frontier in condens…
Evidence for the topological order in a kagome antiferromagnet
Yuan Wei, Zili Feng, Wiebke Lohstroh +19
A Z2 quantum spin liquid hosts one of the simplest topological orders and exhibits many exotic properties due to long-range quantum entanglements. Its elementary excitations are an…
Static and Fluctuating Magnetic Moments in the Ferroelectric Metal LiOsO
Franziska K. K. Kirschner, Franz Lang, Francis L. Pratt +5
LiOsO is the first example of a new class of material called a ferroelectric metal. We performed zero-field and longitudinal-field SR, along with a combination of electronic…
Evidence of Electron-Hole Imbalance in WTe2 from High-Resolution Angle-Resolved Photoemission Spectroscopy
Chenlu Wang, Yan Zhang, Jianwei Huang +25
WTe2 has attracted a great deal of attention because it exhibits extremely large and nonsaturating magnetoresistance. The underlying origin of such a giant magnetoresistance is sti…
Pressure-induced melting of magnetic order and emergence of new quantum state in alpha-RuCl3
Zhe Wang, Jing Guo, F. F. Tafti +19
Here we report the observation of pressure-induced melting of antiferromagnetic (AFM) order and emergence of a new quantum state in the honeycomb-lattice halide alpha-RuCl3, a cand…
Interplay of Dirac electrons and magnetism in AMnBi2 (A=Ca, Sr)
Anmin Zhang, Changle Liu, Changjiang Yi +8
Dirac materials exhibit intriguing low-energy carrier dynamics that offer a fertile ground for novel physics discovery. Of particular interest is the interplay of Dirac carriers wi…
Raman scattering study of large magnetoresistance semimetals TaAs and NbAs
Feng Jin, Xiaoli Ma, Pengjie Guo +12
We have performed polarized and temperature-dependent Raman scattering measurements on extremely large magnetoresitance compounds TaAs and NbAs. In both crystals, all the R…
Raman phonons in the ferroelectric-like metal LiOsO
Feng Jin, Anmin Zhang, Jianting Ji +6
The novel ferroelectric-like structural transition observed in metallic LiOsO [Y. Shi et al., Nat. Mater. 12, 1024 (2013)], has invoked many theoretical and experimental intere…
Spindynamics in the antiferromagnetic phases of the Dirac metals MnBi ( Sr, Ca)
Marein C. Rahn, Andrew J. Princep, Andrea Piovano +4
The square Bi layers in MnBi ( Sr, Ca) host Dirac fermions which coexist with antiferromagnetic order on the Mn sublattice below K (Sr) and $270\,…
