Controlling Fano profiles via conical intersections
Controlling Fano profiles via conical intersections
An analytical model for Fano resonances in two-channel systems is presented. By developing a two-potential formula, we find that the line-shape parameter $q$ factors into a background contribution ${q}_{b}$ that depends only on the uncoupled channels and an interaction contribution ${q}_{i}$ that is affected by the coupling between the channels, …
