Unexpected increase of intensity-dependent excitonic second- and third-harmonic generation induced by static electric fields
Ruixin Zuo, Matthias Reichelt, Cong Ngo +3
We compute and analyze the dependence of excitonic second- and third-harmonic generation (SHG/THG) as a function of the optical excitation intensity in the presence of static elect…
Decoding electron tunnelling delay time by embracing wave-particle duality
Chuncheng Wang, Xiaokai Li, Xiwang Liu +7
Tunnelling lies at the heart of quantum mechanics and is a fundamental process in attosecond science, molecular biology, and quantum devices. Whether tunnelling takes time and how…
Microscopic analysis of high harmonic generation in semiconductors with degenerate bands
Le Huu Thong, Cong Ngo, Huynh Thanh Duc +2
Based on the multiband semiconductor Bloch equations a microscopic approach to high-harmonic generation in crystalline solids which is able to properly describe degenerate bands an…
Effect of Stark shift on low-energy interference structure in strong-field ionization
Weifeng Yang, Jie Li, Wenbin Jia +5
An improved quantum trajectory Monte Carlo method involving the Stark shift of the initial state, Coulomb potential, and multielectron polarization-induced dipole potential is used…
Deep Learning for Feynman's Path Integral in Strong-Field Time-Dependent Dynamics
Xiwang Liu, Guojun Zhang, Jie Li +6
Feynman's path integral approach is to sum over all possible spatio-temporal paths to reproduce the quantum wave function and the corresponding time evolution, which has enormous p…
Low-Energy Interference Structure with Attosecond Temporal Resolution
Xiaohong Song, Wenbin Jia, Xiwang Liu +7
Accessing precisely to the phase variation of electronic wave-packet (EWP) provides unprecedented spatiotemporal information of microworld. A radial interference pattern at near-ze…
Enhanced high harmonic generation in semiconductors by the excitation with multi-color pulses

Momentum mapping of continuum electron wave packet interference
Weifeng Yang, Huatang Zhang, Cheng Lin +5
We analyze the two-dimensional photoelectrons momentum distribution of Ar atom ionized by midinfrared laser pulses and mainly concentrate on the energy range below 2Up. By using a…
Unraveling nonadiabatic ionization and Coulomb potential effects in strong-field photoelectron holography
Xiaohong Song, Cheng Lin, Zhihao Sheng +6
Strong field photoelectron holography has been proposed as a means for interrogating the spatial and temporal information of electrons and ions in a dynamic system. After ionizatio…
Attosecond Interference Induced by Coulomb-Field-Driven Transverse Backward-Scattering Electron Wave-Packets
Xiaohong Song, Peng Liu, Cheng Lin +9
A novel and universal interference structure is found in the photoelectron momentum distribution of atoms in intense infrared laser field. Theoretical analysis shows that this stru…
Shortcut to adiabaticity for an interacting Bose-Einstein condensate
Jean-François Schaff, Xiao-Li Song, Pablo Capuzzi +2
We present an investigation of the fast decompression of a three-dimensional (3D) Bose-Einstein condensate (BEC) at finite temperature using an engineered trajectory for the harmon…
Fast optimal transition between two equilibrium states
Jean-François Schaff, Xiao-Li Song, Patrizia Vignolo +1
We demonstrate a technique based on invariants of motion for a time-dependent Hamiltonian, allowing a fast transition to a final state identical in theory to that obtained through…
