标题： Strong Field Ionization as an Inhomogeneous Schroedinger Equation

摘要： 强场电离由于需要同时精确处理束缚态动力学和有效处理连续态动力学，在理论上难以处理。我们通过将含时薛定谔方程（TDSE）分解为非齐次形式来解决这个问题，在这种形式中，预先计算的束缚态作为含时隧穿分量的源项。当使用精确传播时，由此产生的理论等价于完整的TDSE，并且当传播被近似时，它减少了或消除了波函数误差的主要来源。由此得出的理论的规范不变性被用来澄清在强场S矩阵理论背景下长期观察到的规范依赖性。 显示英文摘要

摘要： Strong field ionization is difficult to treat theoretically due to the simultaneous need to treat bound state dynamics accurately and continuum dynamics efficiently. We address this problem by decomposing the time dependent Schroedinger equation (TDSE) into an inhomogeneous form, in which a precomputed bound state acts as a source term for a time dependent tunneling component. The resulting theory is equivalent to the full TDSE when exact propagation is used, and reduces or eliminates a major source of wavefunction error when propagation is approximated. The gauge invariance of the resulting theory is used to clarify an apparent gauge dependence which has long been observed in the context of strong field S-matrix theory.
