Fano Resonance

Fano resonance is a phenomenon observed in various fields, such as physics and optics, where two different pathways can lead to the same outcome, like a particle absorbing light. One pathway is direct and straightforward, while the other is indirect and involves interference effects. When these paths interact, they can create sharp peaks and dips in the energy levels of the system, resembling a signature in a spectrum. This effect helps explain many processes in nature, from atomic energy levels to the behavior of materials and even how certain technologies, like sensors and lasers, operate efficiently.
