摘要:

本文研究具有简单拓扑的度量图上的平稳sine-Gordon方程。由通量守恒和星图顶点导数的匹配提供顶点边界条件。得到了精确的解析解。它表明,该方法可以扩展到树和其他简单的图形拓扑结构。讨论了所得结果在分支平面约瑟夫森结和三晶界约瑟夫森结中的应用。

英文摘要:

We consider the stationary sine-Gordon equation on metric graphs with simple topologies. The vertex boundary conditions are provided by flux conservation and matching of derivatives at the star graph vertex. Exact analytical solutions are obtained. It is shown that the method can be extended for tree and other simple graph topologies. Applications of the obtained results to branched planar Josephson junctions and Josephson junctions with tricrystal boundaries are discussed.
