无规范超引力中具有超标度破坏的类Lifshitz解

Lifshitz-like solutions with hyperscaling violation in ungauged supergravity

Pablo Bueno, Wissam Chemissany, Patrick Meessen, Tomas Ortin, C. S. Shahbazi

摘要:

本文描述了从已知的无规范超引力理论的黑洞和黑膜解构造非平凡引力解的几种方法,这些解的“近视界”和“近奇点”极限是具有动力学临界指数z、“超标度破坏”指数θ和依赖于原始黑洞解物理参数的Lifshitz半径\ell的类Lifshitz时空.由于新的类利夫希茨解可以从任何无规范超引力的任何黑洞解构造出来,所以它们中的许多可以很容易地嵌入到弦论中。一些程序产生超对称类Lifshitz解决方案。

英文摘要:

In this note we describe several procedures to construct, from known black-hole and black-brane solutions of any ungauged supergravity theory, non-trivial gravitational solutions whose "near-horizon" and "near-singularity" limits are Lifshitz-like spacetimes with dynamical critical exponent z, "hyperscaling violation" exponent θand Lifshitz radius \ell that depends on the physical parameters of the original black-hole solution. Since the new Lifshitz-like solutions can be constructed from any black-hole solution of any ungauged supergravity, many of them can be easily embedded in String Theory. Some of the procedures produce supersymmetric Lifshitz-like solutions.
