in the landscape picture, the disappearance of a flux line or other change of topology is a quantum jump over a mountain ridge into a lower valley.
在地景图像里,一条通量线的消失或其他拓扑的改变,就代表一个翻越山脊进入低谷的量子跃迁。
using the periodic orbit theory, we computed the quantum level density of a particle in the two-dimensional harmonic oscillator potential with and without the magnetic flux line for different cases.
