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…

Spontaneous gap opening and potential excitonic states in an ideal Dirac semimetal TaPdTe

Peng Zhang, Yuyang Dong, Dayu Yan +19

The opening of an energy gap in the electronic structure generally indicates the presence of interactions. In materials with low carrier density and short screening length, long-ra…

Unveiling phase diagram of the lightly doped high-Tc cuprate superconductors with disorder removed

Kifu Kurokawa, Shunsuke Isono, Yoshimitsu Kohama +11

The currently established electronic phase diagram of cuprates is based on a study of single- and double-layered compounds. These CuO planes, however, are directly contacted wi…

Multipole polaron in the devil's staircase of CeSb

Y. Arai, Kenta Kuroda, T. Nomoto +17

Rare-earth intermetallic compounds exhibit rich phenomena induced by the interplay between localized orbitals and conduction electrons. However, since the energy scale of the c…

Visualization of the strain-induced topological phase transition in a quasi-one-dimensional superconductor TaSe3

Chun Lin, Masayuki Ochi, Ryo Noguchi +18

Control of the phase transition from topological to normal insulators can allow for an on/off switching of spin current. While topological phase transitions have been realized by e…

Observation of small Fermi pockets protected by clean CuO2 sheets of a high-Tc superconductor

So Kunisada, Shunsuke Isono, Yoshimitsu Kohama +15

The superconductivity of high transition temperature (Tc) occurs in copper oxides with carrier-doping to an antiferromagnetic (AF) Mott insulator. This discovery more than thirty y…

Material design with the van der Waals stacking of bismuth-halide chains realizing a higher-order topological insulator

Ryo Noguchi, Masaru Kobayashi, Zhanzhi Jiang +28

The van der Waals (vdW) materials with low dimensions have been extensively studied as a platform to generate exotic quantum properties. Advancing this view, a great deal of attent…
