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…
Integrated and DC-powered superconducting microcomb
Chen-Guang Wang, Wuyue Xu, Chong Li +21
Frequency combs, specialized laser sources emitting multiple equidistant frequency lines, have revolutionized science and technology with unprecedented precision and versatility. R…
Unconventional superconducting diode effects via antisymmetry and antisymmetry breaking
Chong Li, Yang-Yang Lyu, Wen-Cheng Yue +19
Symmetry-breaking plays a pivotal role in unlocking intriguing properties and functionalities in material systems. For example, the breaking of spatial and temporal symmetries lead…
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…
Maximizing switching current of superconductor nanowires via improved impedance matching
Labao Zhang, Xiachao Yan, Xiaoqing Jia +3
The temporary resistance triggered by phase slip will result in the switching of superconductor nanowire to a permanent normal state, decreasing the switching current. In this lett…
