AdS2中的孤子激发

Solitonic Excitations in AdS2

Pierre Heidmann, Anthony Houppe

AI总结:

本文利用Ernst形式技巧构造了渐近AdS2并以光滑高维帽终结的超引力孤子解,证明其对应空AdS2中由M2膜通量支撑的非超对称有限能量激发,并与全息对偶CFT1的正则态相关。

摘要:

我们构造了大型超引力解族,这些解渐近趋于AdS$_2$,并以一个在二维中奇异但在更高维中光滑的“帽”终结。这些解破坏了超对称性和共形不变性。我们列举了若干论据,表明它们对应于空AdS$_2$中的有限能量激发,这些激发通过诱导非平凡的泡状拓扑对几何产生反作用。它们是利用与超引力中AdS$_D\times\mathcal{C}$孤子的Ernst形式相关的全新技巧构造的\cite{Bah:2022pdn}。该技巧被应用于M理论中$D=2$且$\mathcal{C}=\\,$S$^3\times$T$^6$的情形。$\mathcal{C}$的方向以一连串螺栓的方式光滑退化,这些螺栓在红外端终止时空,并产生由M2膜通量支撑的非超对称泡。某些特定解具有“平坦”方向,其中泡的大小完全不受约束,可以任意调节,而渐近结构保持固定。这些孤子应对应于全息对偶CFT$_1$的正则非超对称态。

英文摘要:

We construct large families of supergravity solutions that are asymptotic to AdS$_2$ and terminate with a cap that is singular in two dimensions but smooth in higher dimensions. These solutions break supersymmetry and conformal invariance. We list arguments suggesting that they correspond to finite-energy excitations in empty AdS$_2$ that back-react on the geometry by inducing non-trivial bubbling topology. They are constructed from the novel technique associated with the Ernst formalism for AdS$_D\times\mathcal{C}$ solitons in supergravity \cite{Bah:2022pdn}. The technique is applied to $D=2$ in M-theory with $\mathcal{C}=\,$S$^3\times$T$^6$. The directions of $\mathcal{C}$ degenerate smoothly as a chain of bolts which ends the spacetime in the IR and generates non-supersymmetric bubbles supported by M2-brane flux. Some specific solutions have ``flat'' directions where the sizes of their bubbles are totally unconstrained and can be arbitrarily tuned while the asymptotics remains fixed. The solitons should correspond to regular non-supersymmetric states of a holographically dual CFT$_1$.
