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…
Ultrafast Orbital-Selective Photodoping Melts Charge Order in Overdoped Bi-based Cuprates
Xinyi Jiang, Qizhi Li, Qingzheng Qiu +10
High-temperature superconductivity in cuprates remains one of the enduring puzzles of condensed matter physics, with charge order (CO) playing a central yet elusive role, particula…
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…
Selective excitation of collective modes in multiband superconductor MgB2
Jiayu Yuan, Liyu Shi, Tiequan Xu +7
Recent developments in nonequilibrium and nonlinear terahertz (THz) spectroscopies have significantly advanced our understanding of collective excitations in superconductors. Howev…
Transient Higgs oscillations and high-order nonlinear light-Higgs coupling in terahertz-wave drivenNbN superconductor
Z. X. Wang, J. R. Xue, H. K. Shi +6
We study the nonlinear optical response in a superconducting NbN thin film with strong terahertz (THz)wave. Besides the expected third harmonic generation, we observe a new transie…
