Biographical Sketch:

I obtained my B.S. from Beihang University in 2008 and my Ph.D. in theoretic physics from Institute of Physics, Chinese Academy of Sciences (IOP, CAS) in 2013. Then I worked at the physics department of College of William & Mary as a postdoctoral research associate. In 2014, I also joined “The Simons Collaboration on the Many Electron Problem” as an affiliated scientist. I joined the School of Physics and Astronomy at Shanghai Jiao Tong University as a tenure-track associate professor in January of 2019. My research focus on strongly correlated many-body systems in condensed matter physics (high-Tc superconductivity, spin liquid, etc.). My interest lies in the development and improvement of numerical methods for strongly correlated systems, including Quantum Monte Carlo, Density Matrix Renormalization Group, and tensor network states related methods.Wedeveloped a scheme to optimize the trial wave-function in constrained path auxiliary field Quantum Monte Carlo method self-consistently, which reduces the systematic error and makes this method more reliable. We systematically investigated the ground state of two-dimensional Hubbard model. With collaborators, we established the stripe phase as the ground state of two-dimensional Hubbard model. I have published more than 20 papers in peer-reviewed journals, including Science, Phys. Rev. Lett and Phys. Rev. X. There are several Ph.D and postdoctoral positions opening in my group. Please contact me if interested.
