q形变动力学与约瑟夫森结
q-deformed dynamics and Josephson junction
摘要：
我们定义了一个广义速率方程的量子力学中的一个观察，它涉及到一个参数q和其极限$q\to 1$给出了标准的海森堡方程。利用广义速率方程研究了电流偏置约瑟夫森结的动力学行为。据观察，这个玩具模型纳入衍射等效应的临界电流。给出了q的物理解释，并证明q是形变参数。
英文摘要：
We define a generalized rate equation for an observable in quantum mechanics, that involves a parameter q and whose limit $q\to 1$ gives the standard Heisenberg equation. The generalized rate equation is used to study dynamics of current biased Josephson junction. It is observed that this toy model incorporates diffraction like effects in the critical current. Physical interpretation for q is provided which is also shown to be q-deformation parameter.
