????????科研简介：
????????（1）使用 Stripe模型研究了高温超导体和磁性材料的微观机理，首先提出了量子临界相的Wess-Zumino-Witten模式和自旋波激发在高能情况下呈现高度相似性，和实验结果吻合的很好。有关结果被美国国家研究委员会凝聚态物理和材料物理分会在《CMMP2010 报告》中列为未来重要科研课题之一讨论。目前在研究超导与磁性的关系。
????????（2）提出了铁基超导体的磁性模型，研究了多轨道特性，发现了该类材料具有很强的层间相互作用和层内各向异性。提出了磁有序可以导致低温光电子谱（ARPES）呈现各向异性，发现了电子关联效应可以导致电荷分布的Stripe相，给出了基于Hubbard模型的物理相图。与合作者最先提出了基于铁基超导体的三明治约瑟夫森结。
????????（3）通过研究二维量子无序自旋系统，指出在量子情况下著名的Harris指标不遵守。研究了准二维量子自旋系统，发现了磁化率、结构因子的普适规律，可用于快速计算层间相互作用。研究了具有4自旋环状相互作用的Heisenberg模型，显示其不同于传统二级相变的特性，与Deconfined的量子相变密切关联。
????????（4）在新的二维几何阻挫系统-三角Kagome系统的研究上取得一系列成果，获得了伊辛模型、量子+伊辛模型、二聚体模型的精确配分函数（类似Onsager精确解），给出了零温熵，计算了磁化率、比热，得到了外加磁场和有相互作用情况下体系的丰富相图，发现了具有拓扑性质的新自旋相，特别是闭路气体相（Kagome loop gas）。目前在探索新的几何阻挫系统和物质相。
????????（5）研究了拓扑绝缘体的表面磁性RKKY相互作用，指出可以通过电学的方法来调控相互作用的大小和方向，提出了奇异量子Hall效应。目前在考虑拓扑绝缘体与光的相互作用。
????????（6）与合作者提出了石墨烯体系的d+id超导对称性,计算了Andreev 导电谱,《Science》上的超导-石墨烯实验和我们的预测一致。目前在探索石墨烯在量子计算中的应用。
