Overview of Academic Research

Prof. Xu’s research interest is in theoretical development and study on quantum statistical dynamics, spectroscopy, and control of complex systems and has achieved a series of progress in quantum dissipative dynamics. Her major achievements include:

1.Systematic development of an efficient, optimized, and rigorous, non-perturbative quantum hierarchical equation of motion (HEOM) method together with applications to various dynamic mechanisms such as charge/energy transfer reactions.

2.Systematic development of a dissipaton equation of motion (DEOM) method which provides a physical quasi-particle picture of the auxiliary density operators in HEOM. Thus DEOM is able to be straightforwardly and conveniently extended to the study of environmental polarized dynamics and control and nonlinear coupling scenarios.

3.Systematic establishment of the system-bath entanglement theorem (SBET) which focuses on correlation/response functions covering processes including from linear response to strong field excitation, control and photothermal effects. The SBET connects different scales rigorously and largely reduces the computing cost without any loss of information, such as non-Markovianity and cross-scale correlations. It thus provides an approach to investigate the large-scale effects based on only small center system computing.
