Skyrme-Faddeev模型中的纽结

Knots in the Skyrme-Faddeev model

Paul Sutcliffe

摘要:

Skyrme-Faddeev模型是三维空间中一种改进的西格玛模型,它具有按整数值Hopf荷分类的类弦拓扑孤子。数值模拟计算孤子解的霍普夫费用高达16,提供的初始条件由家庭的有理映射从三个球到复杂的投影线。大量的新的解决方案,包括各种环面结的范围内的霍普夫收费。通常这些节点只是局部能量极小值,全局极小值是一个链接的解决方案,但对于某些值的霍普夫电荷,他们是很好的候选人的全局最小能量解决方案。计算的能量与Ward的束缚能界一致。

英文摘要:

The Skyrme-Faddeev model is a modified sigma model in three-dimensional space, which has string-like topological solitons classified by the integer-valued Hopf charge. Numerical simulations are performed to compute soliton solutions for Hopf charges up to sixteen, with initial conditions provided by families of rational maps from the three-sphere into the complex projective line. A large number of new solutions are presented, including a variety of torus knots for a range of Hopf charges. Often these knots are only local energy minima, with the global minimum being a linked solution, but for some values of the Hopf charge they are good candidates for the global minimum energy solution. The computed energies are in agreement with Ward's conjectured energy bound.
