摘要

本文讨论了在各种强相关系统中计算费米子传播子的问题,这些系统可以映射到费米子耦合到(过)阻尼玻色子模式的理论。回顾了许多先前应用的方法及其结果,包括传统的图解恢复和eikonal技术,以及“实验”高维玻色子化和广义(即“自下而上”或“非ads /非cft”)全息猜想。总的来说,这些结果似乎仍然相互冲突或不完整,从而表明这一普遍问题的最终解决办法尚未找到。

Novel approaches to generic non-Fermi liquids: higher- dimensional bosonization vs generalized holography
This paper addresses the problem of computing fermion propagators in a broad variety of strongly correlated systems that can be mapped onto the theory of fermions coupled to an (over)damped bosonic mode. A number of the previously applied approaches and their results are reviewed, including the conventional diagrammatic resummation and eikonal technique, as well as the ‘experimental’ higher-dimensional bosonization and generalized (i.e. ‘bottom-up’ or ‘non-AdS/non-CFT’) holographic conjecture. It appears that, by and large, those results remain either in conflict or incomplete, thereby suggesting that the ultimate solution to this ubiquitous problem is yet to be found.
