各向异性膜的热力学

Thermodynamics of anisotropic branes

Daniel Ávila, Daniel Fernández, Leonardo Patiño, Diego Trancanelli

摘要:

本文研究了嵌入在IIB型超引力各向异性黑膜溶液中的味D 7-膜的热力学性质。味膜在“闵可夫斯基嵌入”和“黑洞嵌入”之间经历相变,在“闵可夫斯基嵌入”中味膜位于视界之外,在“黑洞嵌入”中味膜落入视界。这种转变取决于黑洞的温度,它的各向异性程度,以及味自由度的质量。它要么发生在临界温度,要么发生在临界各向异性。我们从这个分析中学到的一般教训是,在这个特定的实现中,各向异性引起与温度类似的效应。特别是,增加各向异性会使膜越来越多地弯曲到视界中。此外,我们观察到,过渡变得更平滑的各向异性。

英文摘要:

We study the thermodynamics of flavor D7-branes embedded in an anisotropic black brane solution of type IIB supergravity. The flavor branes undergo a phase transition between a `Minkowski embedding', in which they lie outside of the horizon, and a `black hole embedding', in which they fall into the horizon. This transition depends on the black hole temperature, its degree of anisotropy, and the mass of the flavor degrees of freedom. It happens either at a critical temperature or at a critical anisotropy. A general lesson we learn from this analysis is that the anisotropy, in this particular realization, induces similar effects as the temperature. In particular, increasing the anisotropy bends the branes more and more into the horizon. Moreover, we observe that the transition becomes smoother for higher anisotropies.
