相交非超对称膜与闭弦快子凝聚

Intersecting non-SUSY branes and closed string tachyon condensation

J. X. Lu, Shibaji Roy, Zhao-Long Wang, Rong-Jun Wu

摘要:

继\cite{Bai:2006vv}之后,我们在这里考虑表示带电的非超对称$p$ -膜(对于$1\leq p \leq 6$)与II型弦论的不带电的非超对称1-膜和0-膜相交的超引力解。我们展示了这些解决方案如何很好地插值之间的黑色$p$ -膜和卡鲁扎-克莱因“泡沫的没有”(BON)通过连续变化的一些参数表征的解决方案从一组值到另一个。通过对时间对称的一般气泡初始数据分析,我们证明了插值意味着只有对于$p\leq 4$,才有可能从黑$p$ -膜过渡到KK BON,因为在这些情况下,在一定条件下存在局部稳定的静态气泡.然而,对于$p>4$,黑膜总是衰变成动力学泡。与文献中已知的相反,我们认为在一定条件下,导致这种过渡到稳定的静态气泡的机制可以是所有$p\leq 4$的闭弦快子凝聚。我们还表明,配置确实包含(不带电)F-弦所需的封闭弦快子出现导致过渡发生。

英文摘要:

Following \cite{Bai:2006vv} we here consider the supergravity solutions representing the charged non-supersymmetric $p$-brane (for $1\leq p \leq 6$) intersecting with chargeless non-supersymmetric 1-brane and 0-brane of type II string theories. We show how these solutions nicely interpolate between black $p$-branes and the Kaluza-Klein "bubble of nothing" (BON) by continuously varying some parameters characterizing the solutions from one set of values to another. By performing a time symmetric general bubble initial data analysis, we show that the interpolation implies a possible transition from black $p$-branes to KK BON only for $p\leq 4$, as in these cases there exist locally stable static bubbles under certain conditions. However, for $p>4$, black branes always decay into dynamical bubbles. Contrary to what is known in the literature, we argue that under certain conditions, the mechanism causing this transition to stable static bubbles can be the closed string tachyon condensation for all $p\leq 4$. We also show that the configurations indeed contain (chargeless) F-strings required for the closed string tachyons to appear causing the transitions to occur.
