强电子-声子相互作用下的量子点腔QED

Quantum Dot Cavity-QED in the Presence of Strong Electron-Phonon Interactions

I. Wilson-Rae, A. Imamoglu

摘要:

量子点与单个高精细光学微腔模的强耦合构成了量子光学的一个新的基本系统。本文在不作Born-Markov近似的情况下,分析了激子-声子相互作用对量子点腔场耦合的影响。分析是基于已被用来研究"自旋玻色子“的哈密顿量的技术。真空拉比分裂的可观测性取决于表征与声子相互作用的谱密度函数的强度和频率依赖性,这两者都可以受到声子限制的影响。

英文摘要:

A quantum dot strongly coupled to a single high finesse optical microcavity mode constitutes a new fundamental system for quantum optics. Here, the effect of exciton-phonon interactions on reversible quantum-dot cavity coupling is analysed without making Born-Markov approximation. The analysis is based on techniques that have been used to study the ``spin boson'' Hamiltonian. Observability of vacuum-Rabi splitting depends on the strength and the frequency dependence of the spectral density function characterizing the interactions with phonons, both of which can be influenced by phonon confinement.
