论文摘要

我们提出了一个新的确切黑洞配置的家族,这是对任意维度中广义的爱因斯坦 - 马克斯韦 - 迪拉顿设置的解决方案。对于任何动态关键指数$ z \ geq 1 $,这些解决方案是渐近的lifshitz。事实证明,非平凡标量场的存在是打破时空各向同性缩放对称性的直接结果。这个黑洞家族接受各种有趣的限制,将其与各向同性和各向异性病例中的知名解决方案联系起来。我们研究了这些现场配置的热力学,表明第一定律得到满足并提供相应的Smarr公式,这两种关系都涉及电贡献。此外,我们表明,对于某个参数区域,具有非零标量场的各向异性场构型是热力学优选的。该观察结果以及对所谓标量条件的直接验证表明,Dilaton场的出现是由于一种类似于自发标量的机制。

We present a new family of exact black hole configurations, which is a solution to a generalized Einstein-Maxwell-Dilaton setup in arbitrary dimension. These solutions are asymptotically Lifshitz for any dynamical critical exponent $z\geq 1$. It turns out that the existence of a nontrivial scalar field is a direct consequence of breaking the spacetime isotropic scaling symmetry. This black hole family accepts various interesting limits that link it to well-known solutions in both the isotropic and anisotropic cases. We study the thermodynamics of these field configurations showing that the first law is satisfied and providing the corresponding Smarr formula, both of these relations account for an electric contribution. Furthermore, we show that for a certain parameter region, the anisotropic field configuration with a nonzero scalar field is thermodynamically preferred. This observation, together with a direct verification of the so-called scalarization conditions, suggest that the emergence of the dilaton field is due to a mechanism similar to spontaneous scalarization.
