论文摘要
我们全息研究了爱因斯坦 - 斯卡尔 - 高斯 - 骨网的标量，其宇宙学常数为负。我们发现，当我们在标量场和高斯 - 骨网曲率校正之间有适当的相互作用时，Schwarzschild-Ads和Reissner-Nordstrom-Ads黑洞都存在不稳定性。我们将这种不稳定与可能的全息标量化联系起来，并在存在宇宙常数的情况下构建相应的毛茸茸的黑洞溶液。使用全息原则，我们期望这样的大量标量化对应于标量头发冷凝的边界描述而不会破坏任何对称性，并且我们计算了系统的相关全息纠缠熵。此外，我们比较了由标量场与高斯 - 骨网络耦合与高斯 - 骨网术和全息超导效应的影响引起的全息标量表的机制，并在存在电磁场的情况下，并揭示其在标量场的有效质量质量中的差异，温度依赖性的属性和光导通的质量。
We holographically investigate the scalarization in the Einstein-Scalar-Gauss-Bonnet gravity with a negative cosmological constant. We find that instability exists for both Schwarzschild-AdS and Reissner-Nordstrom-AdS black holes with planar horizons when we have proper interactions between the scalar field and the Gauss-Bonnet curvature corrections. We relate such instability to possible holographic scalarization and construct the corresponding hairy black hole solutions in the presence of the cosmological constant. Employing the holographic principle we expect that such bulk scalarization corresponds to the boundary description of the scalar hair condensation without breaking any symmetry, and we calculate the related holographic entanglement entropy of the system. Moreover, we compare the mechanisms of the holographic scalarizations caused by the effect of the coupling of the scalar field to the Gauss-Bonnet term and holographic superconductor effect in the presence of an electromagnetic field, and unveil their differences in the effective mass of the scalar field, the temperature dependent property and the optical conductivity.
