I am a research fellow in Center for Computational Quantum Physics (CCQ), the Flatiron institute. My research searches for the emergent physical laws that drives the collective behaviors in real materials, ultracold atomic gases and quantum circuits. For this purpose, I have been leading a team to develop modern theoretical and numerical framework for quantum many-body physics. I am a core member of the Simons Collaboration on the Many Electron Problem, contributing to both research areas Monte Carlo and Real Materials. My long-term research goals include:

  1. Develop a modern quantum field theory of the many electron problem in real materials, then use the field theory to design next-gen ab-initio methods for electronic structure calculations.

  2. Model the multi-particle scattering in semiconductors, superconductors and many other systems, understand how they drive electronic instabilities and other exotic phenomena. Explore possible experimental probes to measure the angle-resolved multi-particle scattering amplitudes.

  3. Searching for the interdisciplinary quantum many-body problems in quantum emulation and quantum computation.

Solving the above problem calls for a new toolbox. For this purpose, I’m leading a team to develop a general-puposed numerical effective field theory (NEFT) framework.
