Short Biography

I finished my undergraduate studies at Beijing Normal University in 2013. After that, I went to the Hong Kong University of Science and Technology and started my postgraduate study. At beginning, I worked on photonics in C. T. Chan’s group and obtained my Mphil degree in 2015. Then I got interested in condensed matter theory and transferred to K. T. Law’s group to pursue my Ph. D degree. After my Ph. D graduation in 2018, I stayed in Law’s group for 2 years as a postdoctoral fellow. In 2020, I moved to the Materials Research Laboratory at MIT and worked with P. A. Lee as a postdoctoral associate. In 2022, I came back and joined the SPST at ShanghaiTech


 

 

 

 

 

 

 

我的研究领域主要集中在凝聚态物理。自上世纪八十年代量子霍尔效应和高温超导现象发现以来,物质中的拓扑态、电子的强关联效应和非常规超导态一直是凝聚态领域中经久不衰的研究热点。近年来,随着单层石墨烯的问世,各式各样的二维量子材料相继涌现,为研究物质的拓扑态、电子的强关联效应和超导态提供了良好的二维材料平台。结合近年来涌现的各式新型二维量子材料,特别是二维过渡金属硫化物、双层有转角石墨烯和二维莫尔超晶格材料等,本课题组将主要用量子场论、平均场理论和群论等方法对材料中的关联绝缘态、拓扑态、超导特性和电磁性质等进行研究。课题组的研究内容注重预言材料中的新物性和新物相,以及解释实验中观测到的新现象。课题组同时对基于新型量子材料的电子实用器件设计具有强烈兴趣。在最近5年,我的研究论文重点涉及了以下内容:

1. 二维莫尔超晶格材料的量子反常霍尔效应;

2. 超导和金属的磁电响应;

3. 1T-TaS2/1T-TaSe2中的量子自旋液体态;

4. 二维过渡金属硫化物的超导态;

5. 量子振荡;

6. 近藤效应;

……

除上述研究内容以外,课题组对自主探索新的研究方向秉持开放的态度。


My research interest mainly focuses on the field of condensed matter. In the field of condensed matter, since the discovery of the fractional quantum Hall effect and the high Tc superconductivity in 1980s, the study has been focused on the topological states, electronic strong correlation effects, and unconventional superconductivity phenomenon for a long time. In recent years, the advent of monolayer graphene has boosted the emergence of various types of new two-dimensional quantum materials, which can serve as good platforms for the study of topological states, strong correlation effects and superconductivity. Considering the emerging various type of two-dimensional quantum materials, especially the two-dimensional transition metal dichalcogenides, twisted bilayer graphene and two-dimensional Moiré superlattice materials, our group will apply quantum field theory, mean field theory and group theory to carry out a series of study on the correlated insulating states, topological states, superconducting states, and electromagnetic properties that are associated with those new quantum materials. The research carried out in our group will focus on the prediction of new physical states and properties that can emerge in the quantum materials, and we will also work on explanations to new experimental observations. Meanwhile, our group have strong interest in developing electronic device with practical applications that are based on the new quantum materials. In the past 5 years, my research works mainly focused on the following topics:

1. Quantum anomalous Hall effect in two-dimensional Moiré superlattice materials;

2. Magnetoelectric effect in metals and superconductors;

3. Quantum spin liquid phase in 1T-TaS2 and 1T-TaSe2;

4. Superconducting states in two-dimensional transition metal dichalcogenides;

5. Quantum oscillations;

6. The Kondo effect;

……

Apart from the research directions mentioned above, I hold open mind to encourage group members to explore other new research directions by themselves.
