论文摘要
在耦合的量子系统中，作用于混合系统的一个组成部分的纯dephasing机制断裂对称性，并启用了在非偶联系统中禁止的光学转变，即纯dephasing浴缸打开层叠的耗散途径。在这里，我们表明该机制使单光子诱导的参数下转换在超耦合的等离子体式Exciton系统中。激子的快速纯dephasing被证明可以支持光子对的产生，作为主要的能量弛豫途径。
In coupled quantum systems pure dephasing mechanisms acting on one constituent of the hybrid system break symmetry and enable optical transitions which are forbidden in the non-coupled system, i.e., the pure dephasing bath opens a cascaded dissipation pathway. Here we show that this mechanism enables single-photon induced parametric down-conversion in an ultrastrongly coupled plasmon-exciton system. Fast pure dephasing of the exciton is shown to support photon pair generation as the dominant energy relaxation pathway.
