Phase-dependent kink collisions and dual critical-velocity branches in the complex sine-Gordon model
Mohammad Mohammadi, Farnaz Eizadbaksh, Vahideh Bagheri
The complex sine-Gordon (CSG) model contains an internal phase degree of freedom that strongly modifies the dynamics of its solitary-wave solutions. We present a numerical study of…

A Numerical Study of Phase-Dependent Kink-Kink Collisions in the Complex Sine-Gordon Model
Mohammad Mohammadi, Farnaz Eizadbaksh, Vahideh Bagheri
We investigate the collision dynamics of complex kink solutions in the complex sine-Gordon (CSG) model, focusing on the influence of the relative phase and initial velocity. The mo…
