A curious correspondence has been known between Landau models and non-linear sigma models: Reinterpreting the base-manifolds of Landau models as field manifolds, the Landau models are transformed to non-linear sigma models with same global and local symmetries. With the idea of the dimensional hierarchy of higher dimensional Landau models, we exploit this correspondence to present a systematic procedure for construction of non-linear sigma models in higher dimensions. We explicitly derive O(2k+1) non-linear sigma models in 2k dimension based on the parent tensor gauge theories that originate from non-Abelian monopoles. The obtained non-linear sigma models turn out to be Skyrme-type non-linear sigma models with O(2k) local symmetry. Through a dimensional reduction of Chern-Simons tensor field theories, we also derive Skyrme-type O(2k) non-linear sigma models in 2k1 dimension. As a unified description, we explore Skyrme-type generic O(d+1) non-linear sigma models and clarify their basic properties, such as stability of soliton configurations, scale invariant solutions, and field configurations of higher winding number.

通过高维Landau模型建立Skyrme型非线性sigma模型

已知Landau模型与非线性sigma模型之间存在奇怪的对应关系:将Landau模型的基本流形重新解释为场流形,将Landau模型转换为具有相同全局和局部对称性的非线性sigma模型。借助高维Landau模型的维层次结构的思想,我们利用这种对应关系提出了构建高维非线性sigma模型的系统程序。我们明确得出Ø2ķ+1个基于源自非阿贝尔单极子的父级张量规理论的2 k维非线性sigma模型。所得的非线性sigma模型证明是Skyrme型非线性sigma模型,其中Ø2ķ局部对称。通过对Chern-Simons张量场理论进行降维,我们还导出了Skyrme型Ø2ķ 非线性sigma模型 2ķ-1个尺寸。作为统一的描述,我们探索Skyrme型通用Ød+1个 非线性sigma模型,并阐明它们的基本属性,例如孤子配置的稳定性,尺度不变解以及更高绕组数的场配置。
