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…
Coherent terahertz magnon-phonon three-wave mixing in a layered antiferromagnet
Liangyue Li, Na Wu, Zhengwang Lin +9
The coherent nonlinear dynamics between collective excitations, such as magnons and phonons, drive emergent phenomena in quantum materials, yet their direct observation remains a c…
Pressure-induced decoupling of the pseudogap and superconductivity in a bilayer cuprate
Yanghao Meng, Wenjin Mao, Liucheng Chen +8
The physical origin of the pseudogap in cuprate superconductors, whether a precursor to superconductivity or a distinct intertwined order, remains an open question. Although hydros…
Efficient photo-Nernst terahertz emission in single heavy-metal films
Lei Wang, Linxuan Song, Elbert E. M. Chia +5
State-of-the-art metallic terahertz (THz) emitters rely predominantly on spintronic heterostructures, where heavy metals serve as passive spin-to-charge converters. Here, we demons…
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…
Hidden phonon-assisted charge density wave transition in BaFe2Al9 revealed by ultrafast optical spectroscopy
Lei Wang, Mingwei Ma, Jiangxu Li +10
The interplay between electronic and lattice degrees of freedom is fundamental to charge density wave (CDW) formation, yet the microscopic origin often remains elusive. Here, we in…
Broad-temperature-range ultrafast terahertz excitation of collective dynamics in polar skyrmions
Wei Li, Sixu Wang, Pai Peng +8
Ultrafast coherent control of electric dipoles using strong terahertz (THz) pulses provides a means to discover hidden phases of materials and potentially leads to applications in…
A Hidden Quantum Paraelectric Phase in SrTiO3 Induced by Terahertz Field
Wei Li, Hanbyul Kim, Xinbo Wang +8
Coherent manipulation of lattice vibrations using ultrafast light pulses enables access to nonequilibrium 'hidden' phases with designed functionalities in quantum materials. Howeve…
Density-wave-like gap evolution in LaNiO under high pressure revealed by ultrafast optical spectroscopy
Yanghao Meng, Yi Yang, Hualei Sun +8
Density wave (DW) order is believed to be correlated with superconductivity in the recently discovered high-temperature superconductor LaNiO. However, experimental inve…
Rashba-splitting-induced topological flat band detected by anomalous resistance oscillations beyond the quantum limit in ZrTe
Dong Xing, Bingbing Tong, Senyang Pan +4
Topological flat band, on which the kinetic energy of topological electrons is quenched, represents a platform for investigating the topological properties of correlated systems. R…
