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…
Iterated Kinks
N. S. Manton, K. Oleś, A. Wereszczyński
A first order equation for a static kink in the presence of an impurity is extended into an iterative scheme. At the first iteration, the solution is the standard kink, but a…
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…
Non-uniqueness of the supersymmetric extension of the -model
Jose M. Queiruga, A. Wereszczynski
We study the supersymmetric extensions of the -model in and dimensions. We show that it is possible to construct non-equivalent supersymmetric versions of a g…
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…
A unified approach to nuclei: The BPS Skyrme Model
C. Adam, C. Naya, J. Sanchez-Guillen +3
We present a concrete model of a low energy effective field theory of QCD, the well-known Skyrme Model. Specifically, we will work with the BPS submodel in order to describe the bi…
Topological energy bounds in generalized Skyrme models
C. Adam, A. Wereszczynski
The Skyrme model has a natural generalization amenable to a standard hamiltonian treatment, consisting of the standard sigma model and the Skyrme terms, a potential, and a certain…
Topological duality between vortices and planar skyrmions in BPS theories with APD symmetries
C. Adam, J. Sanchez-Guillen, A. Wereszczynski +1
The BPS baby Skyrme models are submodels of baby Skyrme models, where the nonlinear sigma model term is suppressed. They have skyrmion solutions saturating a BPS bound, and the cor…
A gauged baby Skyrme model and a novel BPS bound
C. Adam, C. Naya, J. Sanchez-Guillen +1
The baby Skyrme model is a well-known nonlinear field theory supporting topological solitons in two space dimensions. Its action functional consists of a potential term, a kinetic…
The vector BPS Skyrme model
C. Adam, C. Naya, J. Sanchez-Guillen +1
We analyze the vector meson formulation of the BPS Skyrme model in (3+1) dimensions, where the term of sixth power in first derivatives characteristic for the original, integrable…
The vector BPS baby Skyrme model
C. Adam, C. Naya, J. Sanchez-Guillen +1
We investigate the relation between the BPS baby Skyrme model and its vector meson formulation, where the baby Skyrme term is replaced by a coupling between the topological current…
Supersymmetric extensions of K field theories
C. Adam, J. M. Queiruga, J. Sanchez-Guillen +1
We review the recently developed supersymmetric extensions of field theories with non-standard kinetic terms (so-called K field theories) in two an three dimensions. Further, we st…
A BPS Skyrme model
C. Adam, J. Sanchez-Guillen, A. Wereszczynski
Within the set of generalized Skyrme models, we identify a submodel which has both infinitely many symmetries and a Bogomolny bound which is saturated by infinitely many exact soli…
Compact baby skyrmions
C. Adam, P. Klimas, J. Sanchez-Guillen +1
For the baby Skyrme model with a specific potential, compacton solutions, i.e., configurations with a compact support and parabolic approach to the vacuum, are derived. Specificall…
Compact boson stars in K field theories
C. Adam, N. Grandi, P. Klimas +2
We study a scalar field theory with a non-standard kinetic term minimally coupled to gravity. We establish the existence of compact boson stars, that is, static solutions with comp…
Compact shell solitons in K field theories
C. Adam, P. Klimas, J. Sanchez-Guillen +1
Some models providing shell-shaped static solutions with compact support (compactons) in 3+1 and 4+1 dimensions are introduced, and the corresponding exact solutions are calculated…
Pullback of the Volume Form, Integrable Models in Higher Dimensions and Exotic Textures
C. Adam, P. Klimas, J. Sanchez-Guillen +1
A procedure allowing for the construction of Lorentz invariant integrable models living in d+1 dimensional space-time and with an n dimensional target space is provided. Here, inte…
