构造了IIB型超重力超对称D_1-D_5-P黑洞的一类光滑无水平微态几何。我们首先在ADS 3×S 3去耦合极限下工作，并利用该理论的费米子对称性在块体中产生具有显式CFT对偶描述的新的携带动量的微扰。然后，我们使用超引力方程来计算这些扰动的反向反应，并在渐近ADS和渐近平坦的情况下找到完整的非线性解。这些新的几何结构比以前已知的超层解具有更简单的结构。
We construct a new class of smooth horizonless microstate geometries of the supersymmetric D1-D5-P black hole in type IIB supergravity. We first work in the AdS 3× S 3 decoupling limit and use the fermionic symmetries of the theory to generate new momentum carrying perturbations in the bulk that have an explicit CFT dual description. We then use the supergravity equations to calculate the backreaction of these perturbations and find the full non-linear solutions both in the asymptotically AdS and asymptotically flat case. These new geometries have a simpler structure than the previously known superstrata solutions.
