Josephson结中的螺旋林孤子

SPIRAL FOREST SOLITONS IN THE JOSEPHSON JUNCTIONS

超导薄膜表面存在螺旋林结构的事实说明，在由两块超导薄膜弱连接构成的Josephson结中，Josephson电流可能沿螺旋林传导。假定初始时刻Josephson方程的解满足这个要求，可以得到螺旋林孤子解。这些孤子局部为空间螺旋线，整体为螺旋林，并沿螺旋轴向运动；从而较好地描述了沿螺旋林传导的Josephson电流。

The fact there dxisted spiral forest structure on the surface of superconducting film shows that the Josephson current conduct probably in the spiral forest forthe corresponding Josephson junctions. Suppose that solutions of the Josephson equationsatisfy this condition at initial time. Some spiral forest solitons are constructed by a specialmethod. These solitons consist of many spatial spiraIs and move in the direction of the spiral axis, They describe the Josephson current conducted in the spiral forest.
