摘要:

研究了非对称三角形团簇与贮库耦合的亚稳量子动力学。动态是由浴介导的过渡,这在一定程度上需要一个热活化过程。通过调节受抑团簇的激发光谱来控制衰变速率。我们使用主方程的方法和构造过渡算子的多体状态。我们分析了观测量的动力学,揭示了一个激发态和一个磁极化的基态的亚稳性。

英文摘要:

Metastable quantum dynamics of an asymmetric triangular cluster that is coupled to a reservoir is investigated. The dynamics is governed by bath-mediated transitions, which in part require a thermal activation process. The decay rate is controlled by tuning the excitation spectrum of the frustrated cluster. We use the master equation approach and construct transition operators in terms of many-body states. We analyze dynamics of observables and reveal metastability of an excited state and of a magnetically polarized ground state.
