由弦振幅计算D1D5微态几何

D1D5 microstate geometries from string amplitudes

Stefano Giusto, Jose F. Morales, Rodolfo Russo

摘要:

我们通过计算具有混合D1 D5边界条件的圆盘的闭合弦态的发射振幅,再现了D1 D5微态几何的渐近展开。因此,我们提供了一个直接的联系之间的超引力和D-膜描述的D1 D5微观状态在非零弦耦合。微观上,表征微观状态解的轮廓函数被编码在连接D1和D5膜的扭曲开弦态的凝聚物的选择中。

英文摘要:

We reproduce the asymptotic expansion of the D1D5 microstate geometries by computing the emission amplitudes of closed string states from disks with mixed D1D5 boundary conditions. Thus we provide a direct link between the supergravity and D-brane descriptions of the D1D5 microstates at non-zero string coupling. Microscopically, the profile functions characterizing the microstate solutions are encoded in the choice of a condensate for the twisted open string states connecting D1 and D5 branes.
