Room-temperature multistage metastability in a moiré superstructure
B. Q. Lv, Yifan Su, Alfred Zong +16
Metastability is fundamental not only to phase ordering and transitions, but also to a broad range of modern technologies, from memory devices to metallic glasses. In condensed-mat…
Orbital-selective Mottness Driven by Geometric Frustration of Interorbital Hybridization in Pr4Ni3O10
Yidian Li, Mingxin Zhang, Xian Du +22
The interplay among orbital-selective Mott physics, Hund's coupling, tunable structural motifs, and Kondo-like scattering establishes a compelling paradigm for understanding and en…
Spin Excitations and Flat Electronic Bands in a Cr-based Kagome Superconductor
Zehao Wang, Yucheng Guo, Hsiao Yu Huang +33
In the quest for topology- and correlation-driven quantum states, kagome lattice materials have garnered significant interest for their band structures, featuring flat bands (FBs)…
Hund's coupling assisted orbital-selective superconductivity in Ba1-xKxFe2As2
Elena Corbae, Rong Zhang, Cong Li +10
While the superconducting transition temperature of hole-doped Ba_{1-x}K_{x}Fe_{2}As_{2} decreases past optimal doping, superconductivity does not completely disappear even for the…
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…
Pseudogap and Fermi arc induced by Fermi surface nesting in a centrosymmetric skyrmion magnet
Yuyang Dong, Yuto Kinoshita, Masayuki Ochi +12
Skyrmions in noncentrosymmetric materials are believed to occur due to the Dzyaloshinskii-Moriya interaction. By contrast, the skyrmion formation mechanism in centrosymmetric mater…
