We reinvestigate the famous Mollow triplet and show that most of the well-known quantum characteristics of the Mollow triplet—including incoherent emission and a nonstandard dependence of the sidebands on detuning—can be recovered quantitatively using semiclassical dynamics with a classical light field. In fact, by not relying on the rotating wave approximation, a semiclassical model predicts some quantum effects beyond the quantum optical Bloch equation, including higher-order scattering and asymmetric sideband features. This Letter highlights the fact that, with strong intensities, many putatively quantum features of light–matter interactions arise from a simple balance of mean-field electrodynamics and elementary spontaneous emission, which requires minimal computational cost. Our results suggest that the application of semiclassical electrodynamics to problems with strong light–matter coupling in the fields of nanophotonics and superradiance are likely to yield a plethora of new information.

强场条件下相干和非相干发射的预测半经典模型：Mollow Triplet的再研究

我们对著名的莫洛三重态进行了重新研究，结果表明，莫洛三重态的大多数众所周知的量子特征（包括非相干发射以及边带对失谐的非标准依赖性）都可以使用具有经典光场的半经典动力学定量地恢复。实际上，通过不依赖旋转波逼近，一个半经典模型可以预测除量子光学布洛赫方程之外的某些量子效应，包括高阶散射和不对称边带特征。这封信强调了一个事实，即强度很强的情况下，光-质相互作用的许多推定量子特征是由平均场电动力学和基本自发发射的简单平衡产生的，这需要最小的计算成本。
