本文研究了具有膜局部曲率的Randall-Sundrum模型的有限温度性质。在高温下,如所指示的,该理论处于与平面反德西特黑洞对偶的受限相。当辐射子稳定下来时,就像Goldberger-Wise那样,全息一级相变开始了。膜局部曲率有助于径向动能,这使我们能够大大降低临界气泡能量。与以前的结果相反,相变是在更大的值N,共形场论中的自由度的数量。此外,允许TeV膜上的体标量的值变大,与逆反应约束一致。借助于这一事实,我们发现,在参数空间中的一个广泛的区域隧道发生得相当快,即。在零温度下,膜局部曲率最重要的特征是自旋为2的卡鲁扎-克莱因引力子质量的减少和更重的Radion。
We study the finite-temperature properties of the Randall-Sundrum model in the presence of brane-localized curvature. At high temperature, as dictated by, the theory is in a confined phase dual to the planar anti-de Sitter black hole. When the radion is stabilized,á laGoldberger-Wise, aholographicfirst-order phase transition proceeds. The brane-localized curvature contributes to the radion kinetic energy, which allows us to substantially decrease the critical bubble energy. Contrary to previous results, the phase transition is completed at much larger values of N, the number of degrees of freedom in the conformal field theory. Moreover, the value of the bulk scalar on the TeV brane is allowed to become large, consistent with backreaction constraints. Assisted by this fact, we find that for a wide region in the parameter space tunneling happens rather quickly, i.e.,. At zero temperature, the most important signature of brane-localized curvature is the reduction of spin-2 Kaluza-Klein graviton masses and a heavier radion.
