论文摘要
$λ$形式的最简单示例将SU（2）Wess-Zumino-witten模型与SU（2）主手性模型的非亚伯T-Dual（NATD）连接起来。我们分析了旋转弦，其中一个旋转通过插值目标空间的$λ$变形传播。我们表明，除了NATD限制外，情况与未经证明的案件相似。我们证明了常规旋转串要么折叠或圆形，而且几乎退化的旋转串几乎类似点状，快速或缓慢。 $λ$定义的影响既是旋转字符串能量的总体增量，也是折叠和圆形字符串能量之间间隙的扩大。在NATD限制中，我们证明圆圈消失了，快速串认识到Gubser-Klebanov-Polyakov弦的分散关系。
The simplest example of the $λ$-deformation connects the SU(2) Wess-Zumino-Witten model with the non-Abelian T-dual (NATD) of the SU(2) principal chiral model. We analyze spinning strings with one spin propagating through the $λ$-deformation of the target space of the interpolation. We show that the situation apart from the NATD limit parallels the undeformed case. We demonstrate that regular spinning strings are either folded or circular, and that nearly degenerate spinning strings are either nearly point-like, fast, or slow. The effects of the $λ$-deformation are both the overall increment of the energy of spinning strings and the enlargement of the gap between the energies of folded and circular strings. In the NATD limit, we prove that circular strings disappear and that fast strings realize the dispersion relation of Gubser-Klebanov-Polyakov strings.
