中文摘要: 相互作用普遍存在于实际材料中,很多新奇物理现象的出现与相互作用密切相关。无相互作用系统中的拓扑绝缘体是凝聚态物理学中新出现的研究领域,其新奇物理性质引起人们浓厚的研究兴趣。在本项目中我们将这两者联合,利用数值和解析方法系统研究拓扑相中的相互作用效应。通过这些研究内容,我们希望加深对拓扑相中相互作用效应和相互作用引起相变的理解、在相互作用拓扑相中寻找新奇量子态、同时发展处理相互作用的数值算法。

英文摘要: Interaction commonly exists in real materials and underlies many exotic physical phenomena, while non-interacting topological insulator is a new topic in condensed matter physics, which gets many attentions due to their interesting properties. In this project we will combine the two factors and carry out a systematic study on the effect of interaction in the topological phases with numerical and analytical techniques. By this study we expect further understandings on the effect of interaction in the topological phases and the phase transitions induced by interaction, to find new quantum states in interacting topological phases, and to develop numerical algorithm in dealing with interacting systems.
