Abstract The energy exchange between photons and electrons has been investigated theoretically by ab initio approach based on time-dependent density functional theory. Using diamond as a concrete example, three types of resonance and cancellation in the transfer of energy are theoretically observed, that allows one to gain a useful independent insight into the interaction processes of attosecond light pulses with matter. Our results demonstrate the linearity in energy transfer from intense attosecond light pulses to solids, in contrast to the nonlinearity in energy transfer from intense femtosecond light pulses to solids as expected from the conventional point of view, opening new perspectives for attoscience.

控制从强超短光脉冲到晶体的能量转移：阿秒和飞秒机制的比较研究

摘要 光子和电子之间的能量交换已经通过基于时间依赖密度泛函理论的从头算方法进行了理论上的研究。以金刚石为例，理论上观察到能量转移中的三种共振和抵消，这使人们能够对阿秒光脉冲与物质的相互作用过程获得有用的独立见解。我们的结果证明了从强阿秒光脉冲到固体的能量转移是线性的，这与传统观点所预期的从强飞秒光脉冲到固体的能量转移的非线性形成鲜明对比，为阿托科学开辟了新的视角。
