论文摘要
这篇综述提供了有关最新发展及其对我们对二维有机固体物理学新量子现象的理解的影响。我们集中于电荷领域的相变和集体响应，即电子和晶格自由度的耦合的重要性，而压力是无序的有趣作用。在简要介绍了低维有机固体及其晶体学结构之后，我们着重于维度和相互作用以及新兴的量子现象。具有相当大的电子相关性的有机物研究目前研究的重要主题是Mott Metal-Metal-Mus-unsulator相变，电荷顺序和铁电性。高度沮丧的二维系统是建立的模型化合物，用于研究量子旋转液态和具有磁性长距离顺序的竞争。磁和电偶极子的量子无序状态也有独特的例子。当前的理论方法补充了代表性的实验结果。
This review provides a perspective on recent developments and their implications for our understanding of novel quantum phenomena in the physics of two-dimensional organic solids. We concentrate on the phase transitions and collective response in the charge sector, the importance of coupling of electronic and lattice degrees of freedom and stress an intriguing role of disorder. After a brief introduction to low-dimensional organic solids and their crystallographic structures, we focus on the dimensionality and interactions and emergent quantum phenomena. Important topics of current research in organic matter with sizeable electronic correlations are Mott metal-insulator phase transitions, charge order and ferroelectricity. Highly frustrated two-dimensional systems are established model compounds for studying the quantum spin liquid state and the competition with magnetic long-range order. There are also unique examples of quantum disordered state of magnetic and electric dipoles. Representative experimental results are complemented by current theoretical approaches.
