We report experimental evidence identifying acoustic phonons as the principal source of the excitation-induced-dephasing (EID) responsible for the intensity damping of quantum dot excitonic Rabi rotations. The rate of EID is extracted from temperature dependent Rabi rotation measurements of the ground-state excitonic transition, and is found to be in close quantitative agreement with an acoustic-phonon model.
我们报告了实验证据，证明声子是导致量子点激子拉比旋转强度阻尼的激发诱导退相（EID）的主要来源。EID 的速率是从基态激子跃迁的温度相关拉比旋转测量中提取的，并且与声子模型非常吻合。
