本文提出了一种新的方法,可以快速计算斯塔克系统(即均匀场中的系统)中的复杂能量共振态。该技术是基于在动量空间中的移位算子的截断。空间周期和非周期系统的数值结果表明,该方法的极端简单。
A novel method is presented which allows a fast computation of complex energy resonance states in Stark systems, i.e. systems in a homogeneous field. The technique is based on the truncation of a shift-operator in momentum space. Numerical results for space periodic and non-periodic systems illustrate the extreme simplicity of the method.
