BCS-BEC crossover driven by small Fermi pockets of a high-Tc cuprate superconductor
Junhyeok Jeong, Yamato Enomoto, Yoshimitsu Kohama +16
Fermi arcs observed in underdoped cuprates have sparked debate over whether they represent segments of a large Fermi surface or small Fermi pockets. This ambiguity has long hindere…
Superconducting coherence boosted by outer-layer metallic screening in multilayered cuprates
Junhyeok Jeong, Kifu Kurokawa, Shiro Sakai +13
In multilayered high-Tc cuprates with three or more CuO2 layers per unit cell, the inner CuO2 planes (IPs) are spatially separated from the dopant layers and thus remain cleaner th…
Coupling between electrons and charge density wave fluctuation and its possible role in superconductivity
Yeonghoon Lee, Yeahan Sur, Sunghun Kim +12
In most of charge density wave (CDW) systems of different material classes, ranging from traditional correlated systems in low-dimension to recent topological systems with Kagome l…
Direct observation of topological surface state in the topological superconductor 2M-WS2
Soohyun Cho, Soonsang Huh, Yuqiang Fang +15
The quantum spin Hall (QSH) effect has attracted extensive research interest because of the potential applications in spintronics and quantum computing, which is attributable to tw…
Cu doping effects on the electronic structure of Fe1-xCuxSe
Soonsang Huh, Zouyouwei Lu, Youn Sik Kim +8
Using angle-resolved photoemission spectroscopy (ARPES), we studied the evolution of the electronic structure of Fe1-xCuxSe from x = 0 to 0.10. We found that the Cu dopant introduc…
Electronic phase diagram of iron chalcogenide superconductors FeSe1-xSx and FeSe1-yTey
Shaobo Liu, Jie Yuan, Soonsang Huh +13
Here we establish a combined electronic phase diagram of isoelectronic FeSe1-xSx (0.19 > x > 0.0) and FeSe1-yTey (0.04 < y < 1.0) single crystals. The FeSe1-yTey crystals with y =…
Lifted electron pocket and reversed orbital occupancy imbalance in FeSe
Soonsang Huh, Jeongjin Seo, Beomseo Kim +13
The FeSe nematic phase has been the focus of recent research on iron based superconductors (IBSs) due to its unique properties. A number of electronic structure studies were perfor…
Evidence for Helical Hinge Zero Modes in an Fe-Based Superconductor
Mason J. Gray, Josef Freudenstein, Shu Yang F. Zhao +10
Combining topology and superconductivity provides a powerful tool for investigating fundamental physics as well as a route to fault-tolerant quantum computing. There is mounting ev…
