| Popis: | We present various intense laser-driven electron dynamics simulations performed using a Volkov basis set and compare results with other popular choices of basis. The Volkov basis is comprised of plane waves modified by a time-dependent phase factor, allowing for improved accuracy over other representations such as a real-space grid or plane-wave basis. Alternatively, this advantage may be realized by being afforded significantly larger time-step sizes in wave-function propagation techniques. Comparisons of the Volkov basis set to other popular bases have been carried out for model one-dimensional finite and periodic systems as well as three-dimensional systems using time-dependent density functional theory, and the efficiency and accuracy of the Volkov approach have been demonstrated. |
