论文摘要
我们考虑了一条周期性的振荡偶极子，通过远程偶极 - 偶极相互作用进行相互作用，该相互作用嵌入了Cuboid Fakity波导中。我们表明，偶极激发与空腔光子之间的混合可能导致在偶极链末端定位的新状态的出现，这让人联想到电子系统中发现的TAMM表面状态。对极化tamm态形成的至关重要的要求是，腔横截面高于临界大小。高于此阈值，TAMM状态的定位程度高度取决于腔体的大小，因为它们的参与比与腔横截面区域线性尺度缩放。我们的发现对于具有强光耦合的一维系统中的量子限制效应可能很重要。
We consider a periodic chain of oscillating dipoles, interacting via long-range dipole-dipole interactions, embedded inside a cuboid cavity waveguide. We show that the mixing between the dipolar excitations and cavity photons into polaritons can lead to the appearance of new states localized at the ends of the dipolar chain, which are reminiscent of Tamm surface states found in electronic systems. A crucial requirement for the formation of polaritonic Tamm states is that the cavity cross-section is above a critical size. Above this threshold, the degree of localization of the Tamm states is highly dependent on the cavity size, since their participation ratio scales linearly with the cavity cross-sectional area. Our findings may be important for quantum confinement effects in one-dimensional systems with strong light-matter coupling.
