压力的好处:Lifshitz奇点的解决

The Benefits of Stress: Resolution of the Lifshitz Singularity

Ning Bao, Xi Dong, Sarah Harrison, Eva Silverstein

摘要:

通过AdS/CFT对应,Lifshitz时空描述了具有动力学标度的场论($z \neq 1$)。虽然曲率不变量是小的,Lifshitz度量表现出一个零奇点在IR与一个大的潮汐力,激发弦振子模式。然而,Lifshitz不是爱因斯坦方程的真空解-度量是由非平凡的物质内容,必须考虑到在分析测试对象的传播支持。本文研究了具有D 0-膜密度的弦在IR中的相互作用,它支持一类UV-完全$z=2$ Lifshitz结构.我们表明,弦/D-膜散射在雷吉极限显着减缓字符串,防止发散模式的生产和解决可能是奇异的字符串传播。

英文摘要:

Through the AdS/CFT correspondence, Lifshitz spacetimes describe field theories with dynamical scaling ($z \neq 1$). Although curvature invariants are small, the Lifshitz metric exhibits a null singularity in the IR with a large tidal force that excites string oscillator modes. However, Lifshitz is not a vacuum solution of the Einstein equations -- the metric is supported by nontrivial matter content which must be taken into account in analyzing the propagation of test objects. In this paper, we consider the interaction of a string with a D0-brane density in the IR which supports a class of UV-complete $z=2$ Lifshitz constructions. We show that string/D-brane scattering in the Regge limit slows the string significantly, preventing divergent mode production and resolving the would-be singularity in string propagation.
