标题： Holographic Strange Metals for Philosophers and Physicists

摘要： 本文介绍了奇异金属的物理和哲学，奇异金属的特点是其电学和热学性质与常规金属行为不同。此处讨论的异常奇异金属行为出现在铜氧化物高温超导体的正常态中，无法用标准凝聚态物理描述。目前，只能通过全息对偶来描述，即反德西特时空中的四维黑洞。本文首先介绍了奇异金属的理论及具体实验。然后讨论了一些哲学问题，这些问题涉及全息理论的实验证据及其现实主义解释。奇异金属颠倒了解释方向，通常的全息论论证被视为从边界解释整体量子引力理论。相比之下，本文的目标是通过全息理论来解释实验发现的奇异金属的异常特性。 显示英文摘要

摘要： This paper introduces the physics and philosophy of strange metals, which are characterized by unusual electrical and thermal properties that deviate from conventional metallic behaviour. The anomalous strange-metal behaviour discussed here appears in the normal state of a copper-oxide high-temperature superconductor, and it cannot be described using standard condensed-matter physics. Currently, it can only be described through a holographic dual, viz.~a four-dimensional black hole in anti-de Sitter spacetime. This paper first introduces the theory of, and specific experiments carried out on, strange metals. Then it discusses a number of philosophical questions that strange metals open up regarding the experimental evidence for holography and its realist interpretation. Strange metals invert the explanatory arrows, in that usual holographic arguments are seen as giving explanations of the bulk quantum-gravity theory from the boundary. By contrast, the aim here is, by using holography, to explain the experimentally discovered and anomalous properties of strange metals.
