【报告摘要】

Quantum transport through quantum dots provide insight into fundamental aspects of quantum mechanics and have the potential applications for nanotechnology and quantum information processing. In this presentation, we first demonstrate the quantum dynamics of the charge-state coherence in interacting double-dot Aharonov–Bohm (AB) interferometer systems and the related quantum transport properties, such as the transport current and its noise spectrum [1,2]. We then explore the nonequilibirum Kondo mechanism in the noise spectrum of the current tunneling through an Anderson impurity quantum dot [3].  A bridge between the nonequilibrium Kondo noise and the transient current is established. All the studies are based on our established Hierarchical equations-of-motion (HEOM) approach for open quantum systems [4-6].
