研究目的
To review the primary numerical methods for studying high-order harmonic generation in solids and provide a perspective on this field.
研究成果
The paper concludes that TDSE, SBE, and TDDFT are key numerical methods for studying HHG in solids, each with strengths and weaknesses. Future work should focus on improving accuracy, incorporating propagation effects, and exploring the role of Berry curvature.
研究不足
The review highlights challenges such as the difficulty in simulating real materials with TDSE due to model potential limitations, the need for accurate transition dipole phases in SBE, computational intensity of TDDFT, and the importance of considering propagation effects and Berry curvature in all methods.
