摘要：
Correlated system-bath coherence occurs whenever quantum nature of environment cannot be neglected. This is a type of quantum entanglement, which is playing ever increasing roles in many fields of science nowadays. In this talk, I will present a newly developed theory, the dissipaton-equation-of-motion (DEOM) theory, for hybrid system and bath dynamics. With a quasi-particle picture for bath influence, this theory unifies the treatments on three distinct classes of environments, electron bath, phonon bath, and exciton (two-level spin) bath. Not only it recovers the hierarchical equations of motion formation, but also the new theory identities the auxiliary density operators to the quasi-particles dynamics of hybridizing bath. It provides universal evaluations on various correlation functions, including those of hybridizing bath degrees of freedom. Induced bath dynamics could be reflected directly in experimentally measurable quantities, such as Fano resonances and quantum transport current noise spectrum.Some benchmark evaluations on correlated systems in the aforementioned three classes of bath will be presented. Recent advancements include further a comprehensive theory of quantum dissipation in a class of non-Gaussian coupling environment.
