参考Fano型模型的定性类比，我们开发了一个全面的基本机制，在强耦合开放量子系统（OQS）的非马尔可夫浴响应的激光控制。采用收敛的运动方程组（HEOM）数值求解自旋玻色子哈密顿量的主方程，得到了强太赫兹激光脉冲作用下异质结的约化电子密度矩阵.鲁棒性和有效的控制实现增加了一个因素？2非马尔可夫性由可达态的体积的时间演化来度量。研究了这些场对中心系统布居数和相干性的影响，重点讨论了非马尔可夫性的增加与退相干过程减慢之间的关系。
Referring to a Fano-type model qualitative analogy we develop a comprehensive basic mechanism for the laser control of the non-Markovian bath response in strongly coupled Open Quantum Systems (OQS). A converged Hierarchy Equations Of Motion (HEOM) is worked out to numerically solve the master equation of a spin-boson Hamiltonian to reach the reduced electronic density matrix of a heterojunction in the presence of strong THz laser pulses. Robust and efficient control is achieved increasing by a factor ?2 non-Markovianity measured by the time evolution of the volume of accessible states. The consequences of such fields on the central system populations and coherence are examined, putting the emphasis on the relation between the increase of non- Markovianity and the slowing down of decoherence processes.
