Theoretical research will be conducted on the physical properties of strongly correlated quantum liquids. In particular, work will be done on experimental implications of the chiral spin states and other spin liquid states; edge states and the topological order in the fractional quantum Hall states; and, strongly correlated metals in quasi-one-dimensional systems and quasi-two-dimensional systems. The theoretical approach will utilize field theoretic methods. %%% Recent advances in condensed matter theory have emphasized the unity of strongly interacting many-body systems in spatial dimensions less than three. Of noteworthy importance is the study of the fractional quantum Hall effect and high temperature superconductors using the concept of fractional statistics in two- dimensions to describe a unique and new state of matter. This grant will support research on the connections between various strongly interacting condensed matter systems using the theoretical formalism developed for high energy physics.

理论研究将针对密切相关的量子液体的物理特性进行。 特别是，将对手性旋转状态和其他自旋液态的实验意义进行工作； 边缘状态和分数量子厅的拓扑顺序；并且，在准二维系统和准二维系统中密切相关的金属。 理论方法将利用字段理论方法。 %% %%最近的凝结物理论的进步强调了在空间维度中强烈相互作用的多体系统的统一性小于三。 值得注意的重要性是使用分数统计概念在两维中对分数量子厅效应和高温超导体进行了研究，以描述一种独特而新的物质状态。 该赠款将支持针对高能量物理学开发的理论形式主义的各种强烈相互作用的凝结物质系统之间的联系的研究。
