Our group is working on quantum photonics and quantum materials based on solid state. In particular, the research in these two systems focuses on wide-bandgap materials and two-dimensional materials.
The target of wide-bandgap material research is to use the properties of color centers in these materials to perform quantum information applications, especially in diamond, silicon carbide (SiC) and gallium nitride (GaN). (1) The spin information and photon information in these systems, especially the possibility of spin-photon interface and chip integration, make them attractive for quantum network constructions. (2) The robust spin coherence makes them suitable candidates for quantum computing and quantum sensing.
On the two-dimensional material aspect, here are some examples. (1) The spin and valley degree of freedom in 2D materials not only provide addition knobs towards “green electronics” to reduce energy consumptions, as compared to charge degree of freedom; they also provide promising platform for studying emerging quantum phenomenon such as quantum anomalous hall effect. (2) In addition, Moiré system in twisted structure provides flexible system to study quantum many-body problems, especially the physics interaction between Moire trapped excitons and quantum well. (3) Long lifetime dipolar excitons might lead to BEC state for these quasiparticles. (4) 2D magnetism provides an interesting platform for designed spintronics and coupling between quantum systems in different dimensions.
