Attosecond probing of nuclear dynamics with trajectory-resolved high-harmonic spectroscopy
Pengfei Lan, Marc Ruhmann, Lixin He +8
We report attosecond-scale probing of the laser-induced dynamics in molecules. We apply the method of high-harmonic spectroscopy, where laser-driven recolliding electrons on variou…
Time-dependent population imaging for solid high harmonic generation
Xi Liu, Xiaosong Zhu, Pengfei Lan +4
We propose an intuitive method, called time-dependent population imaging (TDPI), to map the dynamical processes of high harmonic generation (HHG) in solids by solving the time-depe…
Scaling law of high harmonic generation in the framework of photon channel
Liang Li, Pengfei Lan, Lixin He +3
Photon channel perspective on high harmonic generation (HHG) is proposed by quantizing both the driving laser and high harmonics. It is shown that the HHG yield can be expressed as…
Helicity reversion in high harmonic generation driven by bichromatic counterrotating circularly polarized laser fields
Xiaofan Zhang, Liang Li, Xiaosong Zhu +4
We investigate the polarization properties of high harmonics generated with the bichromatic counterrotating circularly polarized (BCCP) laser fields by numerically solving time-dep…
The selection rules of high harmonic generation: the symmetries of molecules and laser fields
Xi Liu, Xiaosong Zhu, Liang Li +4
The selection rules of high harmonic generation (HHG) are investigated using three-dimensional time-dependent density functional theory (TDDFT). From the harmonic spectra obtained…

Xiaosong Zhu, Xi Liu, Pengfei Lan +4
We theoretically demonstrate the quenching effect in below-threshold high harmonic generation (HHG) by using the time-dependent density-functional theory (TDDFT) and solving the ti…
Probing rotational wave-packet dynamics with the structural minimum in high-order harmonic spectra
Meiyan Qin, Xiaosong Zhu, Yang Li +3
We investigate the alignment-dependent high-order harmonic spectrum generated from nonadiabatically aligned molecules around the first half rotational revival. It is found that the…
Molecular orbital tomography beyond the plane wave approximation
Yang Li, Xiaosong Zhu, Pengfei Lan +3
The use of plane wave approximation in molecular orbital tomography via high-order harmonic generation has been questioned since it was proposed, owing to the fact that it ignores…

Xiaosong Zhu, Meiyan Qin, Qingbin Zhang +3
The influence of large permanent dipoles on molecular orbital tomography via high-order harmonic generation (HHG) is investigated in this work. It is found that, owing to the modif…
Role of the Coulomb potential on the ellipticity in atomic high-order harmonics generation
Xiaosong Zhu, Meiyan Qin, Qingbin Zhang +3
The role of the Coulomb potential on the generation of elliptically polarized high-order harmonics from atoms driven by elliptically polarized laser is investigated analytically. I…
