Dynamics of Phi^4 Kinks on a Class of Space Dependent Potentials    [PDF]

Jassem Al-Alawi
In this paper we study the dynamics of $\varphi^{4}$ kinks, generated by considering a particular argument of $\varphi^{4}$ field, in the presence of class of smooth space dependent potentials ie. barriers and wells. Various type of these potentials are produced via two-parameter family. These parameters control the shapes, widths and heights of such potentials. The dynamics are presented through the plotting of the trajectories. We compare numerical calculated critical velocities to theoretical calculations.
