Holographic Axion Model: a simple gravitational tool for quantum matter

Matteo Baggioli, Keun-Young Kim, Li Li, Wei-Jia Li

摘要:

这是一个完整的和详尽的审查所谓的全息轴子模型-一个自下而上的全息系统,其特征在于存在一组移位对称标量体场,其轮廓被视为在空间坐标中的线性。这个简单的模型实现了打破平移不变性的对偶场论保留的背景几何的均匀性,因此允许可控和快速的计算。这个模型的用途非常广泛,它们证明了框架的惊人的多功能性。在这篇评论中,我们触及所有的最新方面,这个模型从它的连接与大规模的重力和有效场论,它的作用,在建模的动量耗散和弹性特性结束的所有唯象特征和流体动力学描述。总之,这是一个完整的指南,最常用的模型之一,在应用全息和必读的任何研究人员进入这一领域。

英文摘要:

This is a complete and exhaustive review on the so-called holographic axion model -- a bottom-up holographic system characterized by the presence of a set of shift symmetric scalar bulk fields whose profiles are taken to be linear in the spatial coordinates. This simple model implements the breaking of translational invariance of the dual field theory by retaining the homogeneity of the background geometry and therefore allowing for controllable and fast computations. The usages of this model are very vast and they are a proof of the spectacular versatility of the framework. In this review, we touch upon all the up-to-date aspects of this model from its connection with massive gravity and effective field theories, to its role in modeling momentum dissipation and elastic properties ending with all the phenomenological features and its hydrodynamic description. In summary, this is a complete guide to one of the most used model in Applied Holography and a must-read for any researcher entering this field.
