Strong nonlinear optical response and transient symmetry switching in Type-II Weyl semimetal -WP2
Tianchen Hu, Bo Su, Liyu Shi +13
The topological Weyl semimetals with peculiar band structure exhibit novel nonlinear optical enhancement phenomena even for light at optical wavelengths. While many intriguing nonl…

Revealing the frequency-dependent oscillations in the nonlinear terahertz response induced by the Josephson current
Sijie Zhang, Zhiyuan Sun, Qiaomei Liu +11
Nonlinear responses of superconductors to intense terahertz radiation has been an active research frontier. Using terahertz pump-terahertz probe spectroscopy, we investigate the c-…

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…
