自对偶Hopfions

Self-dual Hopfions

L. A. Ferreira, A. C. Riserio do Bonfim

摘要:

我们构造了3+1维场论的具有非平凡Hopf拓扑荷的静态和含时精确孤子解,目标空间为二维球面S**2.考虑的模型是一个减少所谓的扩展Skyrme-Faddeev理论的去除二次项的领域的衍生物。使用基于共形和目标空间对称性的分析器构造解决方案。这些解是自对偶的,因为它们解的是一阶微分方程,再加上耦合常数的某些条件,就意味着二阶运动方程。的解决方案属于一个子部门的理论与无限数量的本地守恒电流。该方程的轮廓函数对应于Bogomolny方程的sine-Gordon模型。

英文摘要:

We construct static and time-dependent exact soliton solutions with non-trivial Hopf topological charge for a field theory in 3+1 dimensions with the target space being the two dimensional sphere S**2. The model considered is a reduction of the so-called extended Skyrme-Faddeev theory by the removal of the quadratic term in derivatives of the fields. The solutions are constructed using an ansatz based on the conformal and target space symmetries. The solutions are said self-dual because they solve first order differential equations which together with some conditions on the coupling constants, imply the second order equations of motion. The solutions belong to a sub-sector of the theory with an infinite number of local conserved currents. The equation for the profile function of the ansatz corresponds to the Bogomolny equation for the sine-Gordon model.
