One-dimensional model potentials optimized for the calculation of high-order-harmonic-generation spectra

Year: 2024

Type: article

Abstract: Based on the favorable properties of previously used one-dimensional (1D) atomic model potentials, we introduce an upgraded 1D atomic model potential for the 1D simulation of the quantum dynamics of a single active electron atom driven by a strong, linearly polarized near-infrared laser pulse. By comparing numerical simulation results of typical strong-field physics scenarios in 1D and 3D, we show that this upgraded 1D model potential gives single-atom high-order-harmonic-generation spectra with impressively increased accuracy for the most frequently used driving laser pulse parameters.
