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…
