Chiral fermion reversal in chiral crystals
Hang Li, Sheng Xu, Zhi-Cheng Rao +13
In materials chiral fermions such as Weyl fermions are characterized by nonzero chiral charges, which are singular points of Berry curvature in momentum space. Recently, new types…
Angle-resolved photoemission spectroscopy study of crystal electric field in heavy fermion compound CePt2In7
Yang Luo, Chen Zhang, Qi-Yi Wu +19
The three-dimensional electronic structure and Ce 4f electrons of the heavy fermion superconductor CePt2In7 is investigated. Angle-resolved photoemission spectroscopy using variabl…
Reciprocity between local moments and collective magnetic excitations in the phase diagram of BaFe(AsP)
Jonathan Pelliciari, Kenji Ishii, Yaobo Huang +12
Unconventional superconductivity arises at the border between the strong coupling regime with local magnetic moments and the weak coupling regime with itinerant electrons, and stem…
Flat band magnetism and helical magnetic order in Ni-doped SrCoAs
Yu Li, Zhonghao Liu, Zhuang Xu +15
A series of Sr(CoNi)As single crystals was synthesized allowing a comprehensive phase diagram with respect to field, temperature, and chemical substitution to b…
Dirac surface states in intrinsic magnetic topological insulators EuSn2As2 and MnBi2nTe3n+1
Hang Li, Shun-Ye Gao, Shao-Feng Duan +24
In magnetic topological insulators (TIs), the interplay between magnetic order and nontrivial topology can induce fascinating topological quantum phenomena, such as the quantum ano…
Dirac Fermions in Antiferromagnetic FeSn Kagome Lattices with Combined Space Inversion and Time Reversal Symmetry
Zhiyong Lin, Chongze Wang, Pengdong Wang +14
Symmetry principles play a critical role in formulating the fundamental laws of nature, with a large number of symmetry-protected topological states identified in recent studies of…
Experimental evidence of anomalously large superconducting gap on topological surface state of - film
J. -Y. Guan, L. -Y. Kong, L. -Q. Zhou +12
Connate topological superconductor (TSC) combines topological surface states with nodeless superconductivity in a single material, achieving effective -wave pairing without inte…
Coexistence of ferromagnetic and stripe antiferromagnetic spin fluctuations in SrCoAs
Yu Li, Zhiping Yin, Zhonghao Liu +16
We use inelastic neutron scattering to study energy and wave vector dependence of spin fluctuations in SrCoAs, derived from SrFeCoAs iron pnictide supercond…
New classes of chiral topological nodes with non-contractible surface Fermi arcs in CoSi
Z. -C. Rao, H. Li, T. -T. Zhang +18
In condensed matter systems, chiral topological nodes are robust band crossing points in momentum space that carry nonzero Chern numbers. The chirality is manifested by the presenc…
