论文摘要
将偶极旋转共振期间定期电场的量子点电离的最新数值结果与已知的分析方法进行了比较。发现在有限长度的量子线中，数值电离速率比分析速率慢，尤其是当限制电位强烈影响动态时，尤其是对于低驾驶场。尽管如此，当能量越过局部和连续态之间的边界时，分析预测的电离时间与平均能阈值的对应关系令人满意。
Recent numerical results for ionization of quantum dots by periodic electric field during the electric dipole spin resonance are compared with known analytical approaches. It is found that in finite-length quantum wires the numerical ionization rate is slower than the analytical one, especially for low driving field when the confinement potential strongly affects the dynamics. Still, the analytically predicted ionization times are in satisfactory correspondence with mean energy threshold times when the energy crosses the border between localized and continuum states.
