摘要:

在布居俘获中,衰减量子能级的占据保持一个恒定的非零值。我们证明了在非马尔可夫极限下,与非平坦谱环境相互作用的原子-腔系统表现出了这种行为,有效地实现了非经典态的守恒.我们的研究结果可以理解混合固态系统中的腔损耗的作用,并铺平了道路,最近开发的腔量子电动力学系统中的泄漏的正确描述。

英文摘要:

In population trapping the occupation of a decaying quantum level keeps a constant non-zero value. We show that an atom-cavity system interacting with an environment characterized by a non-flat spectrum, in the non-Markovian limit, exhibits such a behavior, effectively realizing the preservation of nonclassical states against dissipation. Our results allow to understand the role of cavity losses in hybrid solid state systems and pave the way to the proper description of leakage in the recently developed cavity quantum electrodynamic systems.
