Radial vibrations of BPS skyrmions
C. Adam, M. Haberichter, T. Romanczukiewicz +1
We study radial vibrations of spherically symmetric skyrmions in the BPS Skyrme model. Concretely, we numerically solve the linearised field equations for small fluctuations in a s…
Head butting sheep: Kink Collisions in the Presence of False Vacua
Jennifer Ashcroft, Minoru Eto, Mareike Haberichter +2
We investigate numerically kink collisions in a dimensional scalar field theory with multiple vacua. The domain wall model we are interested in involves two scalar fields and…
The volume of a soliton
C. Adam, M. Haberichter, A. Wereszczynski
There exists, in general, no unique definition of the size (volume, area, etc., depending on dimension) of a soliton. Here we demonstrate that the geometric volume (area etc.) of a…
Tunneling decay of false domain walls: the silence of the lambs
Mareike Haberichter, Richard MacKenzie, M. B. Paranjape +1
We study the decay of "false" domain walls, which are metastable states of the quantum theory where the true vacuum is trapped inside the wall, with the false vacuum outside. We co…
