We extend and complete our analysis arXiv:1608.02380 and study the induced world volume metrics and Hawking temperatures of all type IIB rotating probe Dp-branes, dual to the temperature of different flavors at finite R-charge, in the Ben Ami–Kuperstein–Sonnenschein holographic models including the effects of spontaneous conformal and chiral flavor symmetry breakdown. The model embeds type IIB probe flavor Dp-branes into the Klebanov-Witten gravity dual of conformal gauge theory, with the embedding parameter, given by the minimal radial extension of the probes, dual to the IR scale of conformal and chiral flavor symmetry breakdown. We show that when the minimal extension is positive definite, the induced world volume metrics of type IIB rotating probe branes admit thermal horizons and Hawking temperatures despite the absence of black holes in the bulk subject to the world volume and topology of the nontrivial internal cycle wrapped by the probe. We also derive the energy–stress tensor of the thermal probes and study their backreaction and energy dissipation. We show that at the IR scale the backreaction is nonnegligible and find the energy can flow from the probes to the bulk, dual to the energy dissipation from the flavor sectors into the gauge theory.

IIB型模型中的Dp膜动力学和热化作用Ben Ami-Kuperstein-Sonnenschein模型

我们扩展并完成了arXiv:1608.02380的分析,并在Ben Ami–Kuperstein–Sonnenschein中研究了所有IIB型旋转探针Dp-bras的诱导世界体积度量和Hawking温度,在有限的R电荷下,两倍于不同口味的温度。全息模型,包括自发的保形和手性风味对称性破坏的影响。该模型将IIB型探针风味Dp分子嵌入到共形规理论的Klebanov-Witten重力对偶中,其嵌入参数(由探针的最小径向扩展给出)对等形和手性风味对称分解的IR标度。我们表明,当最小扩展为正定时,尽管主体中没有黑洞,但受主体包裹的非平凡内部循环的世界体积和拓扑结构的影响,IIB型旋转探针黄铜的感应世界体积度量值仍允许热能层和霍金温度。我们还导出了热探头的能量应力张量,并研究了它们的后反应和能量耗散。我们表明,在红外范围内,背向反应是不可忽略的,发现能量可以从探针流向主体,这是从风味部门到量规理论的能量耗散的两倍。
