kink scattering
Stephen W. Goatham
In this paper, we investigate the scattering of two kinks and derive the real dynamics by solving the appropriate field equation numerically employing a Runga-Kutta method. W…

Dynamics of multi-kinks in the presence of wells and barriers
Stephen W. Goatham, Lucy E. Mannering, Rebecca Hann +1
Sine-Gordon kinks are a much studied integrable system that possesses multi-soliton solutions. Recent studies on sine-Gordon kinks with space-dependent square-well-type potentials…

Fermions, Skyrmions and the 3-Sphere
Stephen W. Goatham, Steffen Krusch
This paper investigates a background charge one Skyrme field chirally coupled to light fermions on the 3-sphere. The Dirac equation for the system commutes with a generalised angul…
