Kink-antikink scattering in the model without static intersoliton forces
C. Adam, K. Oles, T. Romanczukiewicz +1
Kink-antikink scattering in the model is investigated in the limit when the static inter-soliton force vanishes. We observe the formation of spectral walls and, further, iden…
Staccato radiation from the decay of large amplitude oscillons
Patrick Dorey, Tomasz Romanczukiewicz, Yakov Shnir
We study the decay of large amplitude, almost periodic breather-like states in a deformed sine-Gordon model in one spatial dimension. We discover that these objects decay in a stag…
Solvable self-dual impurity models
C. Adam, K. Oles, J. M. Queiruga +2
We find a family of (half) self-dual impurity models such that the self-dual (BPS) sector is exactly solvable, for any spatial distribution of the impurity, both in the topological…
Spectral Walls in Soliton Collisions
C. Adam, K. Oles, T. Romanczukiewicz +1
During defect-antidefect scattering, bound modes frequently disappear into the continuous spectrum before the defects themselves collide. This leads to a structural, nonperturbativ…
Domain walls that do not get stuck on impurities
C. Adam, K. Oles, T. Romanczukiewicz +1
We present a field theoretical model which allows for domain walls that do not get stuck on impurities. For this purpose, we consider a generalized chiral magnet domain wall action…
The model with the BPS preserving defect
C. Adam, T. Romanczukiewicz, A. Wereszczynski
The model is coupled to an impurity in a way that preserves one-half of the BPS property. This means that the antikink-impurity bound state is still a BPS solution, i.e., a z…
