MoMaTune: Model, Match, Then Tune Language Models for Numerical Records

Weimin Lyu, Jingfen Zhang, Lingdao Sha +4

Despite remarkable progress in language understanding and generation, decoder language models continue to exhibit striking failures on numerical data. Numerical examples are typica…

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…

Evolution of the Saddle Point in Antimony Telluride Homologous Superlattices

Yi-Hsin Shen, Shane Smolenski, Ming Wen +13

Combining topological insulators with topological semimetals in the form of homologous superlattices is a promising approach for generating correlated quantum matter based upon Fer…

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…

A robust weak topological insulator in a bismuth halide Bi4Br2I2

Ryo Noguchi, Masaru Kobayashi, Kaishu Kawaguchi +11

We apply a topological material design concept for selecting a bulk topology of 3D crystals by different van-der-Waals stacking of 2D topological insulator layers, and find a bismu…

Observation and control of the weak topological insulator state in ZrTe5

Peng Zhang, Ryo Noguchi, Kenta Kuroda +14

A quantum spin Hall insulator hosts topological states at the one-dimensional edge, along which backscattering by nonmagnetic impurities is strictly prohibited and dissipationless…

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…

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…
