School of Physics, Peking University

Welcome to our Group

Our research focuses on computer simulations of material properties, covering a wide range of first-principles methods in condensed matter physics and theoretical chemistry, as well as some fundamental theories in statistical physics. These methods and theories include, for example: path-integral methods for the description of statistical nuclear quantum effects (closed-path & open-path, distinguishable particles and bosonic or fermionic systems), the instanton method for quantum tunneling, the initial value representation method for quantum dynamics, crystal structure matching for solid-solid phase transitions, non-equilibrium Green's function theory for quantum friction and quantum dragging, and the Yang-Lee theory for phase transitions.
