论文摘要
在本文中,我们研究了两通道的Fano-Anderson模型中连续体(BIC)中界面的形成。我们利用绿色的功能形式主义以及运动方法方程式来分析相关的可观察物,例如传输系数和状态的密度。最重要的是,我们的结果表明,该系统对具有退化杂质水平的对称配置的情况托管了真实的BIC,然后抑制完整的传输通道。最后,我们认为所提出的机制可能与电子和光子系统中BIC的实现有关。
In this article, we study the formation of the bound states in the continuum (BICs) in a two-channel Fano-Anderson model. We employ the Green's function formalism, together with the equation of motion method, to analyze the relevant observables, such as the transmission coefficient and the density of states. Most importantly, our results show that the system hosts true BICs for the case of a symmetric configuration with the degenerate impurity levels, and a complete transmission channel is then suppressed. Finally, we argue that the proposed mechanism could be relevant for the realization of BICs in the electronic and photonic systems.
