動量空間方法計算含時薛丁格方程式及多光子電離現象的研究

Abstract

利用廣義擬似譜法，將波函數轉換至動量空間下運算，可以節省運算量且與實際值誤差不大，能更為簡便的求得所需的結果。之後更可以將這些完備的波函數運用在其他理論方法上，如微擾理論、SFA等，提供一個可以簡單快速的計算工具，來判斷電子在強雷射場下的行為，以及光電子游離的情形。

Quantum mechanical wave function in momentum space with generalized pseudospectral method, we can save the amount of computation and that the error are small, and the result can be obtained with more easily way. Then we can apply those complete set of wave functions to other theory, such as perturbation theory, strong field approximation (SFA), etc., providing a simple and fast calculation tool to determine the motion of photonelectron in a strong laser field.
