A Clash of Kinks: Phase shifts in colliding non-integrable solitons
Mustafa A. Amin, Eugene A. Lim, I-Sheng Yang
We derive a closed-form expression for the phase shift experienced by 1+1 dimensional kinks colliding at ultra-relativistic velocities (gamma v >> 1), valid for arbitrary periodic…

A scattering theory of ultrarelativistic solitons
Mustafa A. Amin, Eugene A. Lim, I-Sheng Yang
We construct a perturbative framework for understanding the collision of solitons (more precisely, solitary waves) in relativistic scalar field theories. Our perturbative framework…

K-Oscillons: Oscillons with Non-Canonical Kinetic Terms
Mustafa A. Amin
Oscillons are long-lived, localized, oscillatory scalar field configurations. In this work we derive a condition for the existence of small-amplitude oscillons (and provide solutio…
