具有单层 CuO2 平面的超导铜氧化物
Superconducting monolayer cuprate with a single CuO2 plane

该参考文献集全面概述了二维（2D）系统的物理特性，重点关注高温超导和量子相变。 相关文献追溯了石墨烯狄拉克费米子的基础性发现，这激发了学界对二维电子行为的兴趣。大量引文详述了铜氧化物超导体（如 $\text{Bi}_2\text{Sr}_2\text{CaCu}_2\text{O}_{8+\delta}$ 和 $\text{La}_{2-x}\text{Sr}_x\text{CuO}_4$）的研究，探讨了包括高温超导、赝能隙、电子向列相以及原子尺度无序效应在内的物理现象。 这些工作的核心是对量子相变的研究，特别是超薄膜和剥离薄片中的超导体-绝缘体及超导体-金属相变。所选文献强调了诸如科斯特利茨-索利斯（Kosterlitz-Thouless）相变、量子格里菲斯（Griffiths）奇点以及“反常金属”本质等理论框架。通过光谱成像扫描隧道显微镜（STM）和输运测量等实验技术与理论建模的结合，这些研究勾勒出了低维材料中电子对称性破缺、拓扑结构和量子涨落之间复杂的相互作用。该系列研究为理解超导极限及量子物质中的涌现相提供了关键参考。
