Aunque ya lleva unos meses publicad, no se porqué todavía no había reseñado aquí mi último artículo científico publicado, centrado en el tema de los gravitones gigantes en Teoría de Cuerdas/M y su relación con la correspondencia AdS/CFT.

Si os interesa, lo tenéis disponible en Arxiv, pero os dejo aquí el abstract

Dielectric 5-Branes and Giant Gravitons in ABJM

We construct a supersymmetric NS5-brane wrapped on a twisted 5-sphere expanding in the $CP^3$ in $AdS_4\times CP^3$, with D0-brane charge. This configuration provides a realization of the stringy exclusion principle in terms of giant D0-branes. In the maximal case the twisted 5-sphere reduces to a $CP^2$ and its energy can be accounted for both by a bound state of $k$ D4-branes wrapping the $CP^2$ and a bound state of $N$ D0-branes, a realization on the gravity side of the symmetry of Young diagrams with $N$ rows and $k$ columns. We discuss some generalizations of this configuration in M-theory carrying angular momentum, some of them with an interpretation as giant gravitons. We provide the microscopical description that allows to explore the region of finite ‘t Hooft coupling.
