Emergent Cooperative Superstructures via Order-Disorder Kinetics in Molecule-Intercalated NbSe2
Taiga Ueda, Hideki Matsuoka, Shungo Aoyagi +12
The design of quantum states at heterointerfaces has enabled a variety of emergent phenomena. Among them, molecular intercalation superlattices have attracted attention as tunable…
Link between Weyl-fermion chirality and spin texture
Kenta Hagiwara, Philipp Rüßmann, Xin Liang Tan +9
Topological semimetals have recently attracted great attention due to prospective applications governed by their peculiar Fermi surfaces. Weyl semimetals host chiral fermions that…
Superconducting gap and pseudogap in the surface states of the iron-based superconductor PrFeAsO studied by angle-resolved photoemission spectroscopy
K. Hagiwara, M. Ishikado, M. Horio +12
In order to study the possible superconductivity at the polar surfaces of 1111-type iron-based superconductors, which is doped with a large amount of holes in spite of the electron…
Extended superconducting dome of electron-doped cuprates after protect annealing revealed by ARPES
C. Lin, T. Adachi, M. Horio +17
The electron-doped cuprates are usually characterized by a more robust antiferromagnetic phase and a much narrower superconducting (SC) dome than those of the hole-doped counterpar…
-wave superconducting gap observed in protect-annealed electron-doped cuprate superconductors PrLaCeCuO
M. Horio, K. Koshiishi, S. Nakata +11
For electron-doped cuprates, the strong suppression of antiferromagnetic spin correlation by efficient reduction annealing by the "protect-annealing" method leads to superconductiv…
Nematicity in the pseudogap state of cuprate superconductors revealed by angle-resolved photoemission spectroscopy
S. Nakata, M. Horio, K. Koshiishi +9
The nature of the pseudogap and its relationship with superconductivity are one of the central issues of cuprate superconductors. Recently, a possible scenario has been proposed th…
Effect of Coulomb interaction on the two-dimensional electronic structure of the van der Waals ferromagnet CrGeTe
M. Suzuki, B. Gao, K. Koshiishi +12
In order to investigate the electronic properties of the semiconducting van der Waals ferromagnet CrGeTe (CGT), where ferromagnetic layers are bonded through van der Wa…

The peculiar metallic electronic states observed in the Kondo insulator, samarium hexaboride (SmB), has stimulated considerable attention among those studying non-trivial elect…
Angle-resolved photoemission spectroscopy of the low-energy electronic structure of superconducting PrCuO driven by oxygen non-stoichiometry
M. Horio, Y. Krockenberger, K. Koshiishi +8
Bulk crystals of electron-doped cuprates with the T'-type structure require both Ce substitutions and reduction annealing for the emergence of superconductivity while the reduction…
Surface Kondo Effect and Non-Trivial Metallic State of the Kondo Insulator YbB12
