研究了一维边缘结中的分布约瑟夫森电流对宏观量子隧穿的影响。导出了整个系统的拉格朗日量的显式表达式，由此得到了隧穿模的约化欧氏作用量。结果可用于计算各种情况下的量子隧穿率。讨论了在这种系统中的量子隧穿测量。
We studied the effect of the distributed Josephson current of a large one-dimensional edge junction on macroscopic quantum tunneling. An explicit expression for the Lagrangian of the whole system was derived from which we obtained the reduced Euclidean action for the tunneling mode. The result can be used to calculate the quantum tunneling rates in various cases. The measurement of quantum tunneling in such a system was also discussed.
