de Sitter空间中的电磁纽结

Electromagnetic knots from de Sitter space

Olaf Lechtenfeld

摘要:

我们通过将场方程简化为粒子在特定三维势场中的牛顿方程并在特殊情况下求解后者,找到了de Sitter空间上的所有解析SU(2)Yang-Mills解。相比之下,德西特空间上的麦克斯韦方程组可以通过在超球坐标中分离它们来一般性地求解。采用一个著名的保角映射之间的(一半)deSitter空间和(未来的一半)Minkowski空间,麦克斯韦解决方案映射到一个完整的基础上的合理的电磁结配置。我们讨论了他们的一些性质,并说明了建设方法与两个非平凡的例子给出的有理函数的复杂性增加。该材料部分基于[1,2]。

英文摘要:

We find all analytic SU(2) Yang-Mills solutions on de Sitter space by reducing the field equations to Newton's equation for a particle in a particular 3d potential and solving the latter in a special case. In contrast, Maxwell's equations on de Sitter space can be solved in generality, by separating them in hysperspherical coordinates. Employing a well-known conformal map between (half of) de Sitter space and (the future half of) Minkowski space, the Maxwell solutions are mapped to a complete basis of rational electromagnetic knot configurations. We discuss some of their properties and illustrate the construction method with two nontrivial examples given by rational functions of increasing complexity. The material is partly based on [1,2].
