本章讨论了平面微腔中电子能量转移的研究。它集中在不同的情况下，假设两个物种之间的电磁耦合不足以产生相干叠加态。相反，耗散过程完全破坏了两个子系统之间的量子力学相干性。在这种情况下，最初定位在一个子系统（通常称为“施主”）上的激发被非相干地转移到第二个子系统（称为“受主”）。最重要的特征是微腔改变了电磁场的模式结构;因此，电磁场介导的所有相互作用也被修改。特别是，偶极-偶极相互作用的问题，这是修改的腔，从理论和实验上解决。腔效应对电磁相互作用的另一个表现是预测了两个空间分离层中的腔-光子介导的激发杂化。本章讨论了平面腔中能量传递的物理过程以及不同耗散过程所起的作用。
Publisher Summary This chapter discusses a study on electronic energy transfer in a planar microcavity. It focuses on different situations assuming that the electromagnetic coupling between two species is not strong enough to produce a coherent superposition of states. Instead, the dissipative processes to completely destroy the quantum-mechanical coherence between the two subsystems are assumed. In such a situation, the excitation, which is initially localized on one subsystem (usually called “donor”), is incoherently transferred to the second subsystem (called “acceptor”). The most important feature is that a microcavity changes the mode structure of an electromagnetic field; thus, all the interactions mediated by the electromagnetic field are also modified. In particular, the problem of the dipole–dipole interaction, which is modified by the cavity, is addressed both theoretically and experimentally. Another manifestation of the cavity effect on the electromagnetic interaction is the prediction of the cavity-photon-mediated hybridization of the excitations in two spatially separated layers. The chapter discusses the physics of the energy transfer in a planar cavity and the roles that different dissipative processes play.
