量子点腔系统中损耗通道之间的竞争:非常规后果

Competition between loss channels in quantum-dot cavity systems: unconventional consequences

A. Vagov, M. Glässl, M. D. Croitoru, V. M. Axt, T. Kuhn

摘要:

我们证明了在量子点腔系统中,声学声子和光子损耗之间的相互作用在系统动力学中引入了新的特征和特征依赖性。特别是,这两种损失机制的联合行动强烈影响从弱到强耦合制度的过渡,以及在非典型的方式的莫洛型光谱的形状。对于弱耦合,其中的光谱退化到一个单一的线,我们预测,它们的宽度随温度的升高而减小。

英文摘要:

We demonstrate that in quantum-dot cavity systems, the interplay between acoustic phonons and photon losses introduces novel features and characteristic dependencies in the system dynamics. In particular, the combined action of both loss mechanisms strongly affects the transition from the weak to the strong coupling regime as well as the shape of Mollow-type spectra in untypical ways. For weak coupling, where the spectra degenerate to a single line, we predict that their widths decrease with rising temperature.
