论文摘要
了解量子系统和超材料中FANO共振的变化，而无序介质中的超低传播是阐明光学相互作用的关键。使用分析理论和数值模拟，我们发现了复杂能平面中传输零的变形下的拓扑结构和运动。我们证明，可以控制零以在传输时间光谱和变速箱变化零收敛时的频率变化速率中创建超大果Lorentzian线。这表明了一种新的超敏检测方法。
Understanding vanishing transmission in Fano resonances in quantum systems and metamaterials, and ultralow transmission in disordered media is key to elucidating optical interactions. Using analytic theory and numerical simulations, we discover the topological structure and motion under deformation of transmission zeros in the complex energy plane. We demonstrate the zeros can be controlled to create ultranarrow Lorentzian lines in spectra of transmission time and diverging rates of frequency change of transmission zeros as they converge. This suggests a new approach to ultrasensitive detection.
