Yahui Zhang joined the department of physics and astronomy at JHU as an assistant professor in 2022. He obtained his PhD in physics from MIT in 2019 and then he was a postdoc scholar at Harvard university during 2019-2021. 
Yahui is working on condensed matter theory with a focus on strongly correlated physics.  Some recent research interests include (1) Pseudogap metal and strange metal in hole doped cuprates;  (2) New physics in t-J model with spin-one holes; (3) Spin liquids and topological phases in moire systems; (4) Quantum hall multilayers; (5) Various exotic quantum criticalities with emergent gauge fields.   Both analytical methods(quantum field theory, parton theory) and numerical methods (DMRG, quantum monte carlo) are employed in his research.
