论文摘要
对具有相同动量密度相同的高斯和非高斯波数据包检查了散射动力学。平均到达时间延迟，停留时间和阶段时间延迟是针对从方屏障散射的波数据包计算的，这表明非高斯波数据包具有与高斯波数据包不同的平均到达时间延迟。这些差异来自非高斯波数据包的动量波函数阶段的非线性项，从而改变了波数据包的自我交互时间。通过调整动量波函数阶段可以实现平均到达时间延迟的控制，而与波数据包能量无关。
Scattering dynamics are examined for Gaussian and non-Gaussian wave packets with identical momentum densities. Average arrival time delays, dwell times, and phase time delays are calculated for wave packets scattering from a square barrier, and it is shown that the non-Gaussian wave packets exhibit different average arrival time delays than the Gaussian wave packets. These differences result from the non-linear terms in the momentum wave function phase of the non-Gaussian wave packets, which alters the self-interaction times of the wave packets. Control of the average arrival time delay can be achieved through adjustment of the momentum wave function phase, independent of wave packet energy and momentum density.
