Overview of Academic Research
Prof. He’s research focuses on the intersection of condensed matter physics and quantum information. Utilizing theoretical calculations and first-principles methods, he explores important physical questions within material systems.
His major achievements include:
Studied electronic localization in crystals and proved that in one-dimensional lattices, the general asymptotic form of Wannier functions and density matrices is the product of power-law and exponential decays.
Derived the general relationship between the exciton fine structure and polarization angle under external pressure in quantum dots, which was experimentally validated, thereby addressing a key challenge in realizing entangled photon sources in quantum dots.
Clarified the magnetoelectric coupling mechanisms in various multiferroic materials.
Led the development of the first-principles calculation software ABACUS.
Developed tensor network and neural network algorithms to solve quantum many-body problems.
Research Directions:
Semiconductor quantum dots and their applications in quantum information
Computational simulations of strongly correlated systems
Development and application of first-principles calculation software
Materials property analysis and simulations in condensed matter physics
