我们构造了一个对偶正则形式理论来研究量子对偶系统。在这样一个系统中,作为电流和电压之间的关系,我们假设的对偶条件。作为一个简单的例子,我们研究了SC / SI / SC结和SI / SC / SI结之间的对偶性。我们推导出了相互对偶系统中相位与粒子数之间的关系。
英文摘要:
We have constructed a theory of dual canonical formalism, to study the quantum dual systems. In such a system, as the relationship between current and voltage of each, we assumed the duality conditions. As a simple example, we examined the duality between the SC / SI / SC junction and SI / SC / SI junction. We derived the relationship between the phase and the number of particles in a dual system of each other.
