我们开发了一个定量半经典公式，用于计算倾斜磁场中通过量子阱的谐振隧道电流。结果表明，电流仅取决于量子阱内的周期轨道。该理论解释了倾斜角 $30^{circ}$ 附近隧道谱的令人费解的演化，这是由相关周期轨道的交换分叉引起的。
We develop a quantitative semiclassical formula for the resonant tunneling current through a quantum well in a tilted magnetic field. It is shown that the current depends only on periodic orbits within the quantum well. The theory explains the puzzling evolution of the tunneling spectra near a tilt angle of $30^{circ}$ as arising from an exchange bifurcation of the relevant periodic orbits.
