关于破缺洛伦兹不变性全息术的几点评论

Comments on Holography with Broken Lorentz Invariance

Ivan Gordeli, Peter Koroteev

摘要:

最近发现了在洛伦兹不变性被破坏的背景下爱因斯坦方程的一族解ArXiv:0712.1136。我们证明了最近由Kachru,Liu和Mulligan在ArXiv:0808.1725中获得的引力解是先前在额外维理论框架中导出的解的一部分。我们展示了能量动量和爱因斯坦张量是如何相关的,并建立了洛伦兹不变性违反参数之间的对应关系。然后证明了在标度参数具有临界值的两种情况下,标量场理论中局域算符的两点关联函数的标度行为是正确的。因此,我们完成了字典的“树级”对偶的所有已知的解决方案的散装理论。最后,我们推测了边界理论的RG流与整体引力解的渐近行为之间的关系。

英文摘要:

Recently a family of solutions of Einstein equations in backgrounds with broken Lorentz invariance was found ArXiv:0712.1136. We show that the gravitational solution recently obtained by Kachru, Liu and Mulligan in ArXiv:0808.1725 is a part of the former solution which was derived earlier in the framework of extra dimensional theories. We show how the energy-momentum and Einstein tensors are related and establish a correspondence between parameters which govern Lorentz invariance violation. Then we demonstrate that scaling behavior of two point correlation functions of local operators in scalar field theory is reproduced correctly for two cases with critical values of scaling parameters. Therefore, we complete the dictionary of "tree-level" duality for all known solutions of the bulk theory. In the end we speculate on relations between RG flow of a boundary theory and asymptotic behavior of gravitational solutions in the bulk.
