包装的五膜

Wrapped Fivebranes Redux

T. Daniel Brennan, Emil J. Martinec

摘要:

奈弗-施瓦茨五膜的近视界区域提供了规范/引力对偶的有趣例子。我们使用世界面弦论中的零规范WZW模型的工具重新审视了包裹和/或相交的五膜结构,揭示了各种例子中五膜喉的有效几何。不同的测量结果在带有AdS 3帽的五膜喉道上产生了线性双折射,提供了关于相应时空CFT双折射的近BPS结构的丰富信息。

英文摘要:

The near-horizon region of Neveu-Schwarz fivebranes provides interesting examples of gauge/gravity duality. We revisit the structure of wrapped and/or intersecting fivebranes using the tools of null-gauged WZW models in worldsheet string theory, revealing the effective geometry of the fivebrane throat in a variety of examples. Variant gaugings yield linear dilaton fivebrane throats with AdS3 caps, providing a wealth of information about the near-BPS structure of the corresponding spacetime CFT duals.
