论文摘要
已证明Epsilon-Near-Zero(ENZ)材料具有独特的电磁特性。在这里,我们提出了与量子发射极(QE)相连的enz纳米颗粒的辐射能带隙的概念。耦合的QE-Nanoparpicle的辐射发射可以在ENZ频率周围显着抑制,否则可以显着增强,从而产生有效的辐射能量带隙。相对于粒径有效地不变,因此是ENZ材料的内在特性。我们的概念还预示着从量化宽松的发射中消除发射的替代途径,该途径可能会在量子信息存储中找到潜在的应用。
Epsilon-near-zero (ENZ) materials have been demonstrated to exhibit unique electromagnetic properties. Here we propose the concept of radiative energy bandgap for an ENZ nanoparticle coupled with a quantum emitter (QE). The radiative emission of the coupled QE-nanoparticle can be significantly suppressed around the ENZ frequency and substantially enhanced otherwise, yielding an effective energy bandgap for radiation. This suppression is effectively invariant with respect to the particle size and is therefore an intrinsic property of the ENZ material. Our concept also heralds an alternative pathway to quench the emission from a QE, which may find potential application in quantum information storage.
