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…
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…
Cooper minimum of high-order harmonic spectra from MgO crystal in an ultrashort laser pulse
Yiting Zhao, Xiaoqin Xu, Shicheng Jiang +3
Cooper minimum structure of high-order harmonic spectra from atoms or molecules has been extensively studied. In this paper, we demonstrate that the crystal harmonic spectra from a…
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…
