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…
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…
Band-selective third-harmonic generation in superconducting MgB: Possible evidence for Higgs amplitude mode in the dirty limit
Sergey Kovalev, Tao Dong, Li-Yu Shi +13
We report on time-resolved linear and nonlinear terahertz spectroscopy of the two-band superconductor MgB with the superconducting transition temperature K. Th…
