经典自旋Skyrmion解
Classically isospinning Skyrmion solutions
摘要：
研究了Skyrme模型中同位旋对拓扑荷$B=1-4,8$经典孤子解的几何形状和能量的影响。在我们的工作中的新方法是，我们研究经典的isospinning Skyrmions超越刚体近似，也就是说，我们明确允许孤子的解决方案变形，打破静态配置的对称性。我们的全三维弛豫计算表明，Isosinning Skyrme孤子的对称性可以显着不同的静态配置。特别是，isospinning Skyrmion解决方案可以分裂成较低电荷的Skyrmion，可以变形成新的解决方案类型，不存在于消失的角频率$ω$或能量简并可以被删除。这些类型的变形已在很大程度上被忽略了在以前的工作模拟原子核的量子化Skyrmion解决方案。
英文摘要：
We investigate how isospin affects the geometrical shape and energy of classical soliton solutions of topological charges $B=1-4,8$ in the Skyrme model. The novel approach in our work is that we study classically isospinning Skyrmions beyond the rigid-body approximation; that is, we explicitly allow the soliton solutions to deform and to break the symmetries of the static configurations. Our fully three-dimensional relaxation calculations reveal that the symmetries of isospinning Skyrme solitons can differ significantly from the ones of the static configurations. In particular, isospinning Skyrmion solutions can break up into lower-charge Skyrmions, can deform into new solution types that do not exist at vanishing angular frequency $ω$ or energy degeneracy can be removed. These types of deformations have been largely ignored in previous work on modeling nuclei by quantized Skyrmion solutions.
