The mathematical discontinuity existing in the phase-difference dynamic model for the Josephson junction results in the challenge of the dynamic analysis on the Josephson junction. Focusing on the non-smooth characteristics of the dynamic model for the long 0- π Josephson junction, two typical local dynamic behaviors, including the moving breather and the semifluxon interaction, are investigated by the structure-preserving approach based on the multi-symplectic idea in this paper. Firstly, the symmetric form with two segmented local conservation laws is derived form the non-smooth sine-Gordon-type model controlling the evolution of the phase-difference in the long 0- π Josephson junction. And then, the numerical experiments on the above local dynamic behaviors are performed using the proposed structure-preserving approach. The novel discoveries on the local dynamic behaviors of the long 0- π Josephson junction include: The non-dissipative characteristic of the ...

0-π长约瑟夫森结的局部动力学行为

约瑟夫森结的相差动态模型中存在的数学不连续性给约瑟夫森结的动力学分析提出了挑战。着眼于长0-π约瑟夫森结动力学模型的非光滑特性,通过基于多辛思想的结构保全方法研究了两个典型的局部动力学行为,包括运动通气孔和半磁通相互作用。在本文中。首先,从非光滑的正弦-Gordon型模型导出具有两个分段局部守恒定律的对称形式,该模型控制长0-π约瑟夫森结中的相差的演化。然后,利用所提出的结构保持方法对上述局部动力行为进行了数值实验。
