标题： Marginally deformed AdS$_5$/CFT$_4$ and spindle-like orbifolds

摘要： 我们使用全息描述研究了${\cal N}=2$、$d=4$长线性quiver CFT的边缘变形。 我们发现了一个两参数族的AdS$_5$解，这些解通常破坏所有超对称性，但通过参数的特定调整可以保留${\cal N}=1$。 我们研究了${\cal N}=2$“父”背景和${\cal N}=1$背景的G-结构，并在所有情况下仔细讨论了电荷的量子化。 对于${\cal N}=1$和${\cal N}=0$的情况，出现了一幅图景，其中“膜”在锥体或其高维类似物上产生反作用。 对边缘变形的对偶共形场论进行了评论，并研究了一些可观测量。 显示英文摘要

摘要： We study marginal deformations of ${\cal N}=2$, $d=4$ long linear quiver CFTs using the holographic description. We find a two-parameter family of AdS$_5$ solutions that generically break all of supersymmetry, but preserve ${\cal N}=1$ for a particular tuning of the parameters. We study the G-structure of the ${\cal N}=2$ ``parent'' and the ${\cal N}=1$ backgrounds and carefully discuss the quantisation of charges in all cases. For the ${\cal N}=1$ and ${\cal N}=0$ cases, a picture emerges with ``branes" back-reacted on either a spindle or its higher dimensional analogue. Comments on the marginally deformed dual CFTs are given, together with the study of some observables.
