Andrew J. Tolley, C. P. Burgess, Claudia de Rham, D. Hoover

摘要:

我们描述了一个广泛的类含时精确波解的6D规范手征超引力与两个紧凑的维度。这些6D解是4D pp-波和Kundt类解的非平凡翘曲推广,并描述了从6D到4D的广泛的一类先前静态紧化(来源于两个3-膜)如何响应沿着非紧化方向之一移动的波。由于我们的方法一般适用于任何高维超引力,它们很可能用于寻找弦论中含时解的超引力极限。6D的解决方案是有趣的,在自己的权利,描述6D冲击波引起的高能粒子的膜,并作为描述的近膜极限的瞬态波前所产生的局部气泡成核事件的膜之一,如可能会发生,如果张力变化相变发生。

英文摘要:

We describe a broad class of time-dependent exact wave solutions to 6D gauged chiral supergravity with two compact dimensions. These 6D solutions are nontrivial warped generalizations of 4D pp-waves and Kundt class solutions and describe how a broad class of previously-static compactifications from 6D to 4D (sourced by two 3-branes) respond to waves moving along one of the uncompactified directions. Because our methods are generally applicable to any higher dimensional supergravity they are likely to be of use for finding the supergravity limit of time-dependent solutions in string theory. The 6D solutions are interesting in their own right, describing 6D shock waves induced by high energy particles on the branes, and as descriptions of the near-brane limit of the transient wavefront arising from a local bubble-nucleation event on one of the branes, such as might occur if a tension-changing phase transition were to occur.
