Temperature-driven sodium-ion dynamical-to-static crossover in the zig-zag ordered phase of NaCoO
Shangfei Wu, Hengxin Tan, Dong Wu +7
The study combines polarization‑resolved Raman spectroscopy and first‑principles calculations to reveal a temperature‑driven dynamical‑to‑static crossover of sodium ions in Na0.5Co…
Multimodal Terahertz Spectroscopy of the Pairing Symmetry and Normal-State Pseudogap in (La,Pr)NiO Films
Shuxiang Xu, Guangdi Zhou, Hao Wang +11
The discovery of ambient-pressure superconductivity in compressively strained (La,Pr)NiO thin films has intensified efforts to identify the pairing mechanism. However,…
Anomalous terahertz nonlinearity in disordered s-wave superconductor close to the superconductor-insulator transition
Hao Wang, Jiayu Yuan, Hongkai Shi +13
Detection of the Higgs mode in superconductors using nonlinear terahertz spectroscopy is a key area of interest in condensed matter physics. We investigate the influence of disorde…
Structural contribution to light-induced gap suppression in TaNiSe
Zijing Chen, Chenhang Xu, Chendi Xie +13
An excitonic insulator is a material that hosts an exotic ground state, where an energy gap opens due to spontaneous condensation of bound electron-hole pairs. TaNiSe is a…
Mn4Al11: A Half-Semimetal Candidate with Anomalous Electronic Behaviors
Shanshan Han, Rongsheng Li, Xingxing Jiang +5
Half-semimetals, characterized by their spin-polarized electronic states, hold significant promise for spintronic applications but remain scarce due to stringent electronic and mag…
Collapse of density wave and emergence of superconductivity in pressurized-LaNiO evidenced by ultrafast spectroscopy
Shuxiang Xu, Hao Wang, Mengwu Huo +7
Recent discoveries of superconductivity in Ruddlesden-Popper nickelates realize a rare category of superconductors. However, the use of high-pressure diamond anvil cells limits spe…
