Fingerprint of the Interbond Electron Hopping in Second-Order Harmonic Generation
Liang Li, Tengfei Huang, Pengfei Lan +6
We experimentally explore the fingerprint of the microscopic electron dynamics in second-order harmonic generation (SHG). It is shown that the interbond electron hopping induces a…
Strong field induced electron density tide in high harmonic generation from solids
Liang Li, Yinfu Zhang, Pengfei Lan +8
In strong laser fields, the electron density in solids can show up tidal motions caused by the laser ``pulling'' on the electrons, which forms an electron density tide (EDT). Howev…
Reciprocal-space-trajectory perspective on high harmonic generation in solids
Liang Li, Pengfei Lan, Xiaosong Zhu +4
We revisit the mechanism of high harmonic generation (HHG) from solids by comparing HHG in laser fields with different ellipticities but constant maximum amplitude. It is shown tha…
High harmonic generation with circularly polarized fields in solid: a quantum trajectory perspective
Liang Li, Pengfei Lan, Xiaosong Zhu +2
We investigate the high harmonic generation (HHG) in solids driven by laser fields with different ellipticities. The HHG spectra show a two-plateau structure within the energy gap…
High-order harmonic generation of doped semiconductor
Tengfei Huang, Xiaosong Zhu, Liang Li +3
We investigate the high-order harmonic generation (HHG) in doped semiconductors. The HHG is simulated with the single-electron time-dependent Schrödinger equation (TDSE). The resul…
