An accurate control over the dynamics of open systems is of great importance for nowadays quantum physics and engineering,such as quantum information proces
We study systematically the non-Markovian decoherence dynamics of a dissipative two-level system,i.e.the so-called spin-boson model.It is interesting to fin
Recent years have witnessed great interest in the topological properties of quantum materials due to its scientific importance as a novel quantum state and
