Contrasting electron-phonon interaction between electron- and hole-doped cuprates
Qinda Guo, Ke-Jun Xu, Magnus H. Berntsen +15
Spin- and charge-lattice interactions are potential key factors in the microscopic mechanism of high-temperature superconductivity in cuprates. Although both interactions can drama…
Anomalous normal state gap in an electron-doped cuprate
Ke-Jun Xu, Junfeng He, Su-Di Chen +11
In the underdoped n-type cuprate Nd2-xCexCuO4, long-ranged antiferromagnetic order reconstructs the Fermi surface, resulting in a putative antiferromagnetic metal with small pocket…
Bogoliubov Quasiparticle on the Gossamer Fermi Surface in Electron-Doped Cuprates
Ke-Jun Xu, Qinda Guo, Makoto Hashimoto +14
In contrast to hole-doped cuprates, electron-doped cuprates consistently exhibit strong antiferromagnetic correlations with a commensurate (π, π) ordering wave vector, leading to t…
Differentiated roles of Lifshitz transition on thermodynamics and superconductivity in La2-xSrxCuO4
Yong Zhong, Zhuoyu Chen, Su-Di Chen +7
The effect of Lifshitz transition on thermodynamics and superconductivity in hole-doped cuprates has been heavily debated but remains an open question. In particular, an observed p…
Identification of a Critical Doping for Charge Order Phenomena in Bi-2212 Cuprates via RIXS
Haiyu Lu, Makoto Hashimoto, Su-Di Chen +16
Identifying quantum critical points (QCPs) and their associated fluctuations may hold the key to unraveling the unusual electronic phenomena observed in cuprate superconductors. Re…
Electronic structure of superconducting nickelates probed by resonant photoemission spectroscopy
Zhuoyu Chen, Motoki Osada, Danfeng Li +14
The discovery of infinite-layer nickelate superconductors has spurred enormous interest. While the Ni cations possess nominally the same 3 configuration as Cu in…
