五维最小超引力中的孤子:局域电荷、奇异遍历区域和对BPS束缚的破坏

Solitons in Five Dimensional Minimal Supergravity: Local Charge, Exotic Ergoregions, and Violations of the BPS Bound

Geoffrey Compère, Keith Copsey, Sophie de Buyl, Robert B. Mann

摘要:

我们描述了五维空间中规范和非规范最小超引力中一类光滑孤子的一些显著特征。孤子是全局渐近平坦的或渐近AdS的,没有任何卡鲁扎-克莱因方向,但包含一个最小的球时,一个周期夹断的时空内部形成的。溶液带有局部磁荷,许多溶液具有相当不寻常的能面。也许最引人注目的是,许多孤子有更多的电荷,或在渐近AdS的情况下,更多的电荷和角动量比通常的BPS限制所允许的。我们评论,但不解决,新的难题,这提出了广告/CFT。

英文摘要:

We describe a number of striking features of a class of smooth solitons in gauged and ungauged minimal supergravity in five dimensions. The solitons are globally asymptotically flat or asymptotically AdS without any Kaluza-Klein directions but contain a minimal sphere formed when a cycle pinches off in the interior of the spacetime. The solutions carry a local magnetic charge and many have rather unusual ergosurfaces. Perhaps most strikingly, many of the solitons have more electric charge or, in the asymptotically AdS case, more electric charge and angular momentum than is allowed by the usual BPS bound. We comment on, but do not resolve, the new puzzle this raises for AdS/CFT.
