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…
Absence of a BCS-BEC crossover in the cuprate superconductors
John Sous, Yu He, Steven A. Kivelson
We examine key aspects of the theory of the Bardeen-Cooper-Schrieffer (BCS) to Bose-Einstein condensation (BEC) crossover, focusing on the temperature dependence of the chemical po…
Superconducting fluctuations in overdoped BiSrCaCuO
Yu He, Su-Di Chen, Zi-Xiang Li +13
Fluctuating superconductivity - vestigial Cooper pairing in the resistive state of a material - is usually associated with low dimensionality, strong disorder or low carrier densit…
The Nematic Energy Scale and the Missing Electron Pocket in FeSe
Ming Yi, Heike Pfau, Yan Zhang +12
Superconductivity emerges in proximity to a nematic phase in most iron-based superconductors. It is therefore important to understand the impact of nematicity on the electronic str…
