Unveiling High-Energy Ultrafast Responses Driven by Fermi-Level Gap Opening in Charge-Density Waves
Qiong Wu, Tianchen Hu, Junhan Huang +8
Ultrafast pump-probe spectroscopy is indispensable for investigating interactions, collective excitations, and nonequilibrium dynamics in superconductors and correlated electron sy…
Revealing Hidden Inversion Symmetry Breaking in ZrTe via Phonon-Assisted Heterodyne Amplification
S. J. Li, J. H. Huang, H. Y. Wu +13
ZrTe is a sensitive topological material where small perturbations can alter its electronic structure. Its equilibrium crystal structure has been widely regarded as centrosymme…
Temperature-driven sodium-ion dynamical-to-static crossover in the zig-zag ordered phase of NaCoO
Shangfei Wu, Hengxin Tan, Dong Wu +7
We employ polarization-resolved Raman spectroscopy combined with first-principles calculations to study the sodium-ion lattice dynamics in a sodium zig-zag ordered cobaltate compou…
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,…
