Short BiographyI 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.
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.
I joined ShanghaiTech very recently and the research group is recruiting students and researchers who are interested in the field of condensed matter. Our group will recruit 1-2 students and 1-2 postdoctoral fellows per year. Our group can provide excellent postdoctoral fellows with highly competative salary (around 300K RMB per year), and help the postdoctoral fellows to apply the in-campus housing at a discount. On the performance, the postdoctoral fellow can apply to transfer to be an assistant researcher if he (or she) wishes. An assistant researcher, unlike the postdoctoral fellow, is a long term job provided by the university. The assistant researcher can get promoted to be an associated researcher and finally become a permanent researcher, and during the promotion process the researcher's salary and benefits get increasd accordingly. Besides the graduate students and postdoctoral fellows, undergraduate students who are interested in condensed matter theory are welcome to conduct research in our group. Applicants who are interested can send the CV to firstname.lastname@example.org by email.
