论文摘要
规范合奏中黑洞（BH）的局部热力学稳定性由恒定全局电荷的特定热量的阳性定义。与能量储层的热力学平衡中的Schwarzschild BHS始终不稳定，而对少量的能量波动，而足够的近乎近距离的Reissner-Nordström/Kerr BHS稳定。可以预见的是，通过连续性，从这种稳定的阶段分支出来的渐近式毛茸茸的BHS也将是局部热力学上的稳定，对于消失的小头发而言。在某些模型中，我们表明情况并非如此，包括从Reissner-Nordström分叉和与Kerr同步分叉的旋转BHS分叉。具体而言，发现准 - 贝尔德BHS在所有全球电荷中都在局部热力学上不稳定，无论在固定的全球电荷下，无论是动态和熵而不是偏爱秃头的电荷的。
The local thermodynamic stability of a black hole (BH) in the canonical ensemble is defined by the positivity of the specific heat at constant global charges. Schwarzschild BHs in thermodynamic equilibrium with an energy reservoir are always unstable against small fluctuations of energy, whereas sufficiently near-extremal Reissner-Nordström/Kerr BHs are stable. One could expect that asymptotically-flat hairy BHs branching off from such stable phases would also be, by continuity, locally thermodynamically stable for vanishingly little hair. We show this is not the case in some models, including scalarized BHs bifurcating from Reissner-Nordström and spinning BHs with synchronized hair bifurcating from Kerr. Specifically, it is found that quasi-bald BHs are locally thermodynamically unstable in the canonical ensemble for all global charges and regardless of being dynamically and entropically preferred over bald ones at fixed global charges.
