(M)2曲折的故事

A tale of (M)2 twists

Christopher Couzens

摘要:

本文研究了四维U $(1)^4$规范超引力下磁荷AdS $_2\times\mathbb{WCP}^{1}_{[n_-,n_+]}$解的参数空间。我们表明,\emph{twist}和\emph{anti-twist}解决方案实现,并给出其存在的磁荷的解决方案方面的限制。我们提供了这两类解决方案的无限家庭在他们的磁荷和重量的orbifold。作为我们分析的副产品,我们得到了一个封闭的形式表达的自由能的4电荷磁解决方案的磁荷和重量$n_{\pm}$。我们还证明了AdS $_2$解是文献中可以找到的渐近AdS $_4$黑洞的近视界.

英文摘要:

We study the parameter space of magnetically charged AdS$_2\times\mathbb{WCP}^{1}_{[n_-,n_+]}$ solutions in 4d U$(1)^4$ gauged STU supergravity. We show that both \emph{twist} and \emph{anti-twist} solutions are realised and give constraints for their existence in terms of the magnetic charges of the solution. We provide infinite families of both classes of solution in terms of their magnetic charges and weights of the orbifold. As a byproduct of our analysis we obtain a closed form expression for the free-energy of the 4-charge magnetic solution in terms of the magnetic charges and weights $n_{\pm}$. We also show that the AdS$_2$ solution is the near-horizon of an asymptotically AdS$_4$ black hole which can be found in the literature.
