Remarkable Enhancement of High Harmonic Generation from Superhard Material under High Pressure
Zishao Wang, Tong Wu, Ziwen Wang +6
High harmonic generation (HHG) in solids offers a pathway to develop compact extreme ultraviolet (EUV) sources crucial for attosecond science and advanced spectroscopy. Here, we de…

Solid-like high harmonic generation from rotationally periodic systems
Yigeng Peng, Tong Wu, Guanglu Yuan +3
High harmonic generation (HHG) from crystals in strong laser fields has been understood by the band theory of solid, which is based on the periodic boundary condition (PBC) of tran…

Electron-Backscattering-Assisted High Harmonic Generation from Bilayer Nanostructures
Chao Yu, Shicheng Jiang, Tong Wu +4
In the framework of time-dependent density functional theory, we obtain high-order harmonics of photon energies up to 10 Up from bilayer crystals with an interlayer spacing d = 70…
