边缘变形环面AdS/CFT中的半经典弦
Semiclassical strings in marginally deformed toric AdS/CFT
摘要：
我们研究β变形的Sasaki-Einstein规范/引力对偶中的弦解。我们发现BPS点弦在两个U（1）圈收缩为零的子流形中运动。在相应的T^3纤维化描述中，弦位于多面体的边缘，在那里T^3纤维化退化为T^1。此外，我们发现，对于每一个变形的Sasaki-Einstein流形的BPS弦的解决方案只存在于特定值的变形参数。我们的结果意味着，在对偶场论中，相应的BPS算子只存在于我们发现的这些特定的变形参数值。我们还研究了非BPS弦，推导了它们的色散关系，并与未变形的弦进行了比较。最后，我们评论的范围内的有效性，我们的解决方案和它们对变形参数的依赖。
英文摘要：
We study string solutions in the beta-deformed Sasaki-Einstein gauge/gravity dualities. We find that the BPS point-like strings move in the submanifolds where the two U(1) circles shrink to zero size. In the corresponding T^3 fibration description, the strings live on the edges of the polyhedron, where the T^3 fibration degenerates to T^1. Moreover, we find that for each deformed Sasaki-Einstein manifold the BPS string solutions exist only for particular values of the deformation parameter. Our results imply that in the dual field theory the corresponding BPS operators exist only for these particular values of the deformation parameter we find. We also examine the non-BPS strings, derive their dispersion relations and compare them with the undeformed ones. Finally, we comment on the range of the validity of our solutions and their dependence on the deformation parameter.
