六维微扰三电荷微态几何

Perturbative 3-charge microstate geometries in six dimensions

Masaki Shigemori

摘要:

利用hep-th/0311092的解生成技术,我们构造了一组代表D1-D5-P三电荷系统的规则微观态的超对称几何。这些解被构造为围绕最大旋转的D1-D5解的线性级扰动,并且依赖于D1-和D5-膜所包裹的S^1的坐标。在Gutowski、Martelli和Reall [hep-th/0306235]提出的六维超引力框架中,这些解有一个依赖于S^1坐标v的四维基。由任意曲面参数化的上层解的基依赖于v,这些解向它们的显式构造迈出了一小步。

英文摘要:

We construct a set of supersymmetric geometries that represent regular microstates of the D1-D5-P 3-charge system, using the solution generating technique of hep-th/0311092. These solutions are constructed as perturbations around the maximally rotating D1-D5 solution at the linear order, and depend on the coordinate of S^1 on which the D1- and D5-branes are wrapped. In the framework of six-dimensional supergravity developed by Gutowski, Martelli and Reall [hep-th/0306235], these solutions have a 4-dimensional base that depend on the S^1 coordinate v. The v-dependent base is expected of the superstratum solutions which are parametrized by arbitrary surfaces, and these solutions give a modest step toward their explicit construction.
