论文摘要
我们开发了一个综合的理论模型，用于微腔设备中一对激子孔之间的相互作用强度。在一个维度中对偶极极性子的数值计算用作建立一个born-oppenheimer理论的起点，该理论通常适用于一个和二维的通用 - 偶性或非二极极极性子。该理论预测，与裸露的激子相比，与腔模式的强耦合会导致极化相互作用的急剧增强，并预测相互作用强度的意外缩放定律随系统参数的函数。绘制了与可用实验数据的比较，并通过新实验进行了具体建议以对其进行验证。终于勾勒出了有希望的观察强大北极封锁制度的有希望的策略。
We develop a comprehensive theoretical model for the interaction strength between a pair of exciton-polaritons in microcavity devices. Ab initio numerical calculations for dipolar polaritons in one dimension are used as a starting point to build a Born-Oppenheimer theory that generally applies to generic -- dipolar or non-dipolar polaritons -- in both one and two dimensions. This theory anticipates that the strong coupling to the cavity mode leads to a drastic enhancement of the polariton interactions as compared to bare excitons, and predicts unexpected scaling laws in the interaction strength as a function of system parameters. Comparisons with available experimental data are drawn, and specific suggestions to validate it with new experiments are made. Promising strategies towards the observation of a strong polariton blockade regime are finally sketched.
