论文摘要

在四个维度中,我们考虑了一个广义标量探测理论,其中耦合函数仅取决于标量场的动力学项。对于此模型,我们获得了一组毛茸茸的抗De-sitter黑洞解决方案,使我们能够根据复杂性等于动作的猜想来计算计算复杂性。为了执行此操作,该系统包含一个在边界上移动的粒子,对应于散装中的基本字符串。效应字符串由Nambu-Goto术语给出,分析该系统的时间开发。与上述相同,我们计算剪切粘度,其中粘度/熵密度比可能违反Kovtun-Son-Starinets,以适当选择偶联功能。

In four dimensions, we consider a generalized scalar-tensor theory where the coupling functions only depend on the kinetic term of the scalar field. For this model, we obtain a set of hairy Anti-de-Sitter black hole solutions, allowing us to calculate the computational complexity, according to the Complexity equals Action conjecture. To perform this, the system contains a particle moving on the boundary, corresponding to the insertion of a fundamental string in the bulk. The effect string is given by the Nambu-Goto term, analyzing the time development of this system. Together with the above, we calculate the shear viscosity, where the viscosity/entropy density ratio can violate the Kovtun-Son-Starinets bound for a suitable choice of coupling functions.
