波包隧道

Wave packet tunneling

H. M. Krenzlin, J. Budczies, K. W. Kehr

摘要:

通过数值求解一维薛定谔方程研究了高斯波包的隧穿。波包与方形障碍物相互作用的形状已被监测的各种值的障碍物的宽度,高度和初始宽度的波包。与自由传播的情况相比,隧穿波包的最大值出现了位移,这可以解释为隧穿过程中速度的增强。

英文摘要:

The tunneling of Gaussian wave packets has been investigated by numerically solving the one-dimensional Schrödinger equation. The shape of wave packets interacting with a square barrier has been monitored for various values of the barrier width, height and initial width of the wave packet. Compared to the case of free propagation, the maximum of a tunneled wave packet exhibits a shift, which can be interpreted as an enhanced velocity during tunneling.
