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…
Ultrafast giant enhancement of second harmonic generation in a strongly correlated cobaltite
Yuchen Cui, Qiaomei Liu, Qiong Wu +15
In quantum materials, nonlinear optical responses are highly sensitive to electronic structure and many-body interactions. Probing and manipulating such nonlinear processes is a co…
Coherent seeding and control of dynamical ferroelectricity by phonon anharmonicity
Junhan Huang, Yongkang Ju, Xinbo Wang +12
Optical control of quantum materials has progressed along two separate directions: creating non-equilibrium states inaccessible at equilibrium, and coherently controlling ultrafast…
Terahertz frequency upconversion by coherently driving charge dynamics in the InSb/CdTe heterostructure
Pai Peng, Mingxiang Pan, Jiuming Liu +10
We investigate terahertz (THz) harmonic generation in the InSb/CdTe heterostructure, demonstrating, for the first time, efficient in-plane magnetic field-induced second-harmonic ge…
Ultrafast Terahertz and Optical Spectroscopy under Synergetic Extreme Conditions
Xinbo Wang, Tao Dong, Jianlin Luo +1
Elucidating and manipulating emergent phases in complex materials requires direct access to their low-energy collective modes. Terahertz (THz) time-domain and ultrafast optical spe…
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,…
