Fano

Fano resonance is a phenomenon where a system exhibits a distinctive asymmetric line shape in its response, caused by the interference between a discrete, localized state and a broad spectrum of states. Imagine a tiny resonator interacting with a continuum of energy pathways; this interaction leads to a sharp dip and peak in how the system absorbs or transmits energy. Fano resonance appears in various fields like optics, acoustics, and quantum physics, providing sensitive means to detect changes and control wave behaviors with high precision due to its unique interference-based profile.
