Catching the geometric phase effect around conical intersection in molecules by high order harmonic spectroscopy
Guanglu Yuan, Ruifeng Lu, Shicheng Jiang +1
Nonadiabatic dynamics around an avoid crossing or a conical intersection play a crucial role in the photoinduced processes of most polyatomic molecules. The present work shows that…

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…
