Head butting sheep: Kink Collisions in the Presence of False Vacua

Ashcroft, Jennifer, Eto, Minoru, Haberichter, Mareike, Nitta, Muneto, Paranjape, Manu (2016) Head butting sheep: Kink Collisions in the Presence of False Vacua. Journal of Physics A: Mathematical and Theoretical, 49 (36). p. 365203. ISSN 1751-8113. E-ISSN 1751-8121. (doi:10.1088/1751-8113/49/36/365203) (KAR id:55207)


We investigate numerically kink collisions in a 1+1 dimensional scalar field theory with multiple vacua. The domain wall model we are interested in involves two scalar fields and a potential term built from an asymmetric double well and (double) sine-Gordon potential together with an interaction term. Depending on the initial kink setup and impact velocities, the model allows for a wide range of scattering behaviours. Kinks can repel each other, annihilate, form true or false domain walls and reflect off each other.
