(1 + 1)维标量场理论的自对偶扇区

Self-dual sectors for scalar field theories in (1 + 1) dimensions

L. A. Ferreira, P. Klimas, Wojtek J. Zakrzewski

摘要:

本文利用广义自对偶条件的思想,构造了具有精确自对偶扇区的(1 + 1)维实标量场理论。该方法是基于一个预电位U,定义了拓扑电荷和势能的这些理论。在我们的代数方法来构建所需的预势,我们使用李群的表示理论。这种方法自然会导致一个无限集的退化真空,从而拓扑非平凡的自对偶解决方案,这些模型。我们给出了SU(2),SU(3)和SO(5)群解的显式例子,并讨论了这些解的一些性质.

英文摘要:

We use ideas of generalized self-duality conditions to construct real scalar field theories in (1 + 1)-dimensions with exact self dual sectors. The approach is based on a pre-potential U that defines the topological charge and the potential energy of these theories. In our algebraic method to construct the required pre-potentials we use the representation theory of Lie groups. This approach leads naturally to an infinite set of degenerate vacua and so to topologically non-trivial self-dual solutions of these models. We present explicit examples for the groups SU(2), SU(3) and SO(5) and discuss some properties of these solutions.
