论文摘要
我们基于已从Bloch转换为Wannier基础的带中电流的半导体中高谐波产生的准经典理论。 Wannier准古典方法揭示了塑造高谐波产生的机制的完整图片，从而获得了具有完整量子计算的定量一致性。准经典波袋传播所揭示的直观图片将有助于对高谐波和Attsecond实验的解释和设计。除此之外，用经典轨迹进行定量模拟量子动力学的能力应被证明可用于更广泛的凝结物质研究，包括相干控制，运输理论和强场物理。
We develop a quasi-classical theory of high harmonic generation in semiconductors based on an interband current that has been transformed from Bloch to Wannier basis. The Wannier quasi-classical approach reveals a complete picture of the mechanisms shaping high harmonic generation, such that quantitative agreement with full quantum calculations is obtained. The intuitive picture revealed by quasi-classical wavepacket propagation will be helpful in the interpretation and design of high harmonic and attosecond experiments. Beyond that, the capacity to quantitatively model quantum dynamics with classical trajectories should prove useful for a wider spectrum of condensed matter research, including coherent control, transport theory, and strong field physics.
