Lifshitz奇点

Lifshitz Singularities

Gary T. Horowitz, Benson Way

摘要:

Lifshitz时空是具有各向异性标度对称性的强耦合场论的可能引力场。然而,这些时空有一个零曲率奇点。我们发现,高维嵌入的Lifshitz也有类似的奇异性。我们研究了测试弦在这种背景下的传播,发现如果它们试图通过奇点传播,它们会变得无限兴奋。这意味着利弗席兹几何是不稳定的,在弦论中会得到很大的修正。

英文摘要:

Lifshitz spacetimes are possible gravitational duals to strongly coupled field theories with an anisotropic scaling symmetry. These spacetimes however, have a null curvature singularity. We find that higher dimensional embeddings of Lifshitz also have a similar singularity. We study the propagation of test strings in this background and find that they become infinitely excited if they try to propagate through the singularity. This means that the Lifshitz geometry is unstable and will receive large corrections in string theory.
