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…
Entropy stabilization and effect of A-site ionic size in bilayer nickelates
Jia-Yi Lu, Jia-Xin Li, Xin-Yu Zhao +5
The discovery of high-temperature superconductivity in LaNiO under high pressure has sparked a surge of research into Ruddlesden-Popper (RP) nickelates. Currently, stab…
Stabilization of Tetragonal Phase and Aluminum-Doping Effect in a Bilayer Nickelate
Jia-Yi Lu, Yi-Qiang Lin, Kai-Xin Ye +7
Recent studies suggest that the tetragonal phase of the Ruddlesden-Popper (RP) bilayer nickelate, LaNiO or LaPrNiO, which is stabilized under high pressures…
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…
Absence of itinerant ferromagnetism in a cobalt-based oxypnictide
Hua-Xun Li, Hao Jiang, Yi-Qiang Lin +5
We report a layered transition-metal-ordered oxypnictide SrCrCoAsO. The new material was synthesized by solid-state reactions under vacuum. It has an intergrowth struct…
