Microscopic Investigation of the Superconducting State in CuCoS: Evidence for an Intermediate-Coupling Fully Gapped Superconductor
K. Panda, A. Bhattacharyya, Liang-Wen Ji +4
The thiospinel compound CuCoS provides an attractive platform for exploring superconductivity in transition-metal chalcogenide spinels. Here, we report the first microscopi…
Altermagnetism and Room-Temperature Metal-to-Insulator Transition in CsCrSO
Yi Liu, Chen-Chao Xu, Jin-Ke Bao +14
Metal-to-insulator transitions (MITs), particularly near room temperature, have been extensively studied in nonmagnetic and conventional ferromagnetic and antiferromagnetic systems…
Tomonaga-Luttinger liquid and charge-density wave in a quasi-one-dimensional material
Jing Li, Guo-Wei Yang, Bai-Zhuo Li +18
In one-dimensional (1D) electron systems, the Fermi liquid state breaks down due either to electron interactions, which results in a Tomonaga-Luttinger liquid (TLL) state, or to Pe…
CsVTe: A Correlated Electron System with Topological Flat Bands
Chang-Chao Liu, Ji-Yong Liu, Jing Li +9
Correlated electron systems with topological flat bands show great promise in exploring exotic quantum phenomena. However, such crystalline materials remain rare. Here we report th…
Physical properties and first-principles calculations of an altermagnet candidate CsVTeO
Chang-Chao Liu, Jing Li, Ji-Yong Liu +4
We report the crystal growth, structure, physical properties, and first-principles calculations of a vanadium-based oxytelluride CsVTeO. The material possesses two…
Quantum Criticality by Interaction Frustration in a Square-Planar Lattice
Yi-Qiang Lin, Chang-Chao Liu, Jia-Xin Li +16
We report experimental and theoretical investigations on ThCrGeC, a metallic compound in which CrC planes form a square-planar lattice. Neutron powder diffraction, magn…
