任意维标量黑膜的超标度破坏

Hyperscaling violation for scalar black branes in arbitrary dimensions

Mariano Cadoni, Matteo Serra

摘要:

本文将文献[1]关于标量黑2-膜的超标度破坏和相变的结果推广到任意维的黑膜。推导了(d+1)维标量孤子在红外共形不变AdS真空和紫外标度协变度规之间插值的解析形式。我们表明,该系统经历了一个相变之间的Schwarzschild-AdS和标量打扮BB。我们计算了这两个阶段的临界指数和超标度破坏参数。我们表明,我们的标量BB解决方案一般出现超引力理论的p-膜解决方案的紧化。我们还推导出短距离形式的标量算子对应的UV指数势支持我们的黑膜解决方案。我们发现,也为负值的超标度破坏参数,这些散射有一个短距离幂律行为。

英文摘要:

We extend to black branes (BB) in arbitrary dimensions the results of Ref. [1] about hyperscaling violation and phase transition for scalar black 2-branes. We derive the analytic form of the (d+1)-dimensional scalar soliton interpolating between a conformal invariant AdS vacuum in the infrared and a scale covariant metric in the ultraviolet. We show that the thermodynamical system undergoes a phase transition between Schwarzschild-AdS and a scalar-dressed BB. We calculate the critical exponent and the hyperscaling violation parameter in the two phases. We show that our scalar BB solutions generically emerge as compactifications of p-brane solutions of supergravity theories. We also derive the short distance form of the correlators for the scalar operators corresponding to an UV exponential potential supporting our black brane solution. We show that also for negative values of the hyperscaling violation parameter these correlators have a short distance power-law behavior.
