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…
How to obtain complex transition dipole moments satisfying crystal symmetry and periodicity from ab-initio calculations
Shicheng Jiang, Chao Yu, Jigen Chen +3
Transition dipole moments (TDM) between energy bands of solids deserve special attention nowadays as intense lasers can easily drive non-adiabatic transitions of excited electron w…
Crystal Symmetry and Polarization of High-order Harmonics in ZnO
Shicheng Jiang, Shima Gholam-Mirzaei, Erin Crites +5
We carried out a joint theoretical and experimental study of the polarization of high-order harmonics generated from ZnO by intense infrared laser pulses. Experimentally we found t…
