摘要：Super-regular breathers play a key role in the exact analytical description of modulation instability developing from a localized periodic modulation. However, finding exact solutions of super-regular breathers in vector fields is a challenge. In this talk, we will show how to construct such exact solutions by eigenvalue analysis and by finding exact link between super-regular breathers and modulation instability, i.e., G(ω) =γ∆Vg. In particular, we will highlight the role of the relation G(ω) =γ∆Vg in revealing the nature of the super-regular breathers in both the scalar and vector nonlinear systems.
