为了求解空间非均匀电磁辐射脉冲中的含时薛定谔方程,我们提出了一种迭代半经典复轨线方法。在数值应用中,我们验证了这种方法againstab inionumerical解决方案,通过仔细研究(a)电子状态的组合库仑和空间均匀的激光场和(B)条纹光电发射从氢原子和等离子体金纳米球。与条纹光电发射计算在强场近似下进行比较,我们证明了改进的空间非均匀诱导等离子体激元红外场附近的纳米粒子表面条纹光电发射光谱重建。
To solve the time-dependent Schrödinger equation in spatially inhomogeneous pulses of electromagnetic radiation, we propose an iterative semiclassical complex trajectory approach. In numerical applications, we validate this method againstab initionumerical solutions by scrutinizing (a) electronic states in combined Coulomb and spatially homogeneous laser fields and (b) streaked photoemission from hydrogen atoms and plasmonic gold nanospheres. In comparison with streaked photoemission calculations performed in strong-field approximation, we demonstrate the improved reconstruction of the spatially inhomogeneous induced plasmonic infrared field near a nanoparticle surface from streaked photoemission spectra.
