黑洞中的玻璃态相变与稳定性

Glassy Phase Transition and Stability in Black Holes

Rabin Banerjee, Sujoy Kumar Modak, Saurav Samanta

摘要:

黑洞热力学,局限于半经典的制度,不能解决的热力学稳定性的黑洞在平坦的空间。在这里,我们表明,包含超过半经典近似的修正,使黑洞磁稳定。这种稳定性是通过相变实现的。通过使用Eschlafest的方案,我们进一步证明了这是一个玻璃态相变的Prigogine-Defay比接近3。该值正好位于玻璃态相变的所需范围(2至5)内。因此,我们的分析表明,一个黑洞的相变现象和玻璃形成系统之间有着非常密切的联系。最后,我们讨论了我们的结果的鲁棒性,通过考虑不同的归一化的校正项。

英文摘要:

Black hole thermodynamics, confined to the semi-classical regime, cannot address the thermodynamic stability of a black hole in flat space. Here we show that inclusion of correction beyond the semi-classical approximation makes a black hole thermodynamically stable. This stability is reached through a phase transition. By using Ehrenfest's scheme we further prove that this is a glassy phase transition with a Prigogine-Defay ratio close to 3. This value is well placed within the desired bound (2 to 5) for a glassy phase transition. Thus our analysis indicates a very close connection between the phase transition phenomena of a black hole and glass forming systems. Finally, we discuss the robustness of our results by considering different normalisations for the correction term.
