Coexistence of High Temperature Superconductivity and Antiferromagnetic Order in a Cuprate with Multiple Hole Fermi Pockets
Xiangyu Luo, Yinghao Li, Hao Chen +23
The intricate relationship between high temperature superconductivity and antiferromagnetic order in cuprates, and the fundamental origin of electron pairing remain open questions.…
Persistent Fermi Pockets and Robust Electron Pairing in Lightly Doped CuO Planes of Cuprate Superconductors
Hao Chen, Jumin Shi, Yinghao Li +23
High temperature superconductivity in cuprate superconductors is generally considered to be generated from doping the Mott insulators. The fundamental nature of the doped parent co…
Unusual Dual Flat Bands and two-dimensional Dirac-node Arc State in Kagome Metal Ni3In2S2
Bo Liang, Yichen Liu, Jie Pang +36
Kagome materials are at the frontier of condensed matter physics. An ideal kagome lattice features only one geometrically frustrated flat band spanning the entire momentum space an…
Neutron Spin Resonance Near a Lifshitz Transition in Overdoped BaKFeAs
Yang Li, Dingsong Wu, Yingjie Shu +11
Elucidating the relationship between spin excitations and fermiology is essential for clarifying the pairing mechanism in iron-based superconductors (FeSCs). Here, we report inelas…
