我们报道了退相干对极化激元双稳性的影响。极化激元磁滞回线被示出以类似的方式崩溃时，增加温度或非共振激发功率下。滞后向上阈值被拉到较低的激励功率，而向下阈值几乎保持恒定。这种效果是由人口的不相干水库，诱导退相和排斥的相互作用，在大密度饱和。所有的实验结果准确地模拟与激子布洛赫方程，并表明，双斜入射诱导的退相可以占主导地位的双斜入射诱导的能量蓝移。
We report on the effect of decoherence on polariton bistability. The polariton hysteresis loop is shown to collapse in a similar way when increasing the temperature or under nonresonant excitation power. The hysteresis upward threshold is pulled to lower excitation power, whereas the downward threshold remains almost constant. This effect is explained by the population of an incoherent reservoir that induces dephasing and repulsive interaction that saturates at large densities. All experimental findings are accurately simulated with the excitonic Bloch equations and indicate that reservoir-induced dephasing can be dominant over the reservoir-induced energy blueshift.
