False-vacuum bubbles in sphaleron scattering
Manuel A. Martínez Sánchez, Christoph Adam, Danial Saadatmand
We investigate the collision dynamics of two bright sphalerons in a (1+1)-dimensional deformed scalar field theory with a symmetric potential possessing false vacua. Two one-…
Moduli Space for Kink Collisions with Moving Center of Mass
Christoph Adam, Chris Halcrow, Katarzyna Oles +2
We apply the collective coordinate model framework to describe collisions of a kink and an antikink with nonzero total momentum, i.e., when the solitons possess different velocitie…
BPS soliton-impurity models and supersymmetry
C. Adam, Jose M. Queiruga, A. Wereszczynski
We find supersymmetric extensions of the half-BPS soliton-impurity models in (1+1) dimensions which preserve half of the supersymmetry. This is related to the fact…
Gauged BPS baby Skyrmions with quantised magnetic flux
C. Adam, A. Wereszczynski
A new type of gauged BPS baby Skyrme model is presented, where the derivative term is just the Schroers current (i.e., gauge invariant and conserved version of the topological curr…
The volume of a vortex and the Bradlow bound
C. Adam, J. M. Speight, A. Wereszczynski
We demonstrate that the geometric volume of a soliton coincides with the thermodynamical volume also for field theories with higher-dimensional vacuum manifolds (e.g., for gauged s…
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…
