维度对偶

Dimensional Duality

Daniel Green, Albion Lawrence, John McGreevy, David R. Morrison, Eva Silverstein

摘要:

我们证明了紧致负曲流形上的弦论,在保持U(1)^{b_1}缠绕对称性的情况下,随着空间的收缩,至少增加了b_1个新的有效维数。绕组电流产生的“D-对偶”描述的黎曼曲面的属h在其2 h维雅可比环面,由一个封闭的字符串快子所产生的世界面西格玛模型中的势能项扰动。这种负弯曲流形上的D-膜也揭示了这种结构,经典的模空间由b_1-环面组成。特别是,我们提出了一个AdS/CFT系统,它提供了一个非微扰制定这样的超临界背景。最后,我们讨论这个新的弦对偶的推广。

英文摘要:

We show that string theory on a compact negatively curved manifold, preserving a U(1)^{b_1} winding symmetry, grows at least b_1 new effective dimensions as the space shrinks. The winding currents yield a "D-dual" description of a Riemann surface of genus h in terms of its 2h dimensional Jacobian torus, perturbed by a closed string tachyon arising as a potential energy term in the worldsheet sigma model. D-branes on such negatively curved manifolds also reveal this structure, with a classical moduli space consisting of a b_1-torus. In particular, we present an AdS/CFT system which offers a non-perturbative formulation of such supercritical backgrounds. Finally, we discuss generalizations of this new string duality.
