Stability and decay of composite kinks/-balls solutions in a deformed linear sigma model
A. Alonso-Izquierdo, D. Canillas Martinez, C. Garzon Sanchez +2
The defect-type solutions of a deformed linear sigma model with a real and complex fields in -dimensional Minkowski spacetime are studied. All the solutions ar…
Construction of new scalar field models from the standard theory
D. Bazeia, M. A. González León, L. Losano +2
In this work we study models described by a single real scalar field in two-dimensional space-time, using the deformation procedure to propose and investigate new families of model…
On domain walls in a Ginzburg-Landau non-linear S^2-sigma model
Alberto Alonso-Izquierdo, Miguel Angel Gonzalez Leon, Juan Mateos Guilarte +1
The domain wall solutions of a Ginzburg-Landau non-linear -sigma hybrid model are unveiled. There are three types of basic topological walls and two types of degenerate famili…
Quantum fluctuations of topological -kinks
A. Alonso Izquierdo, M. A. Gonzalez Leon, J. Mateos Guilarte +1
The kink Casimir effect in the massive non-linear -sigma model is analyzed.
On the semiclassical mass of -kinks
A. Alonso Izquierdo, M. A. Gonzalez Leon, J. Mateos Guilarte +1
One-loop mass shifts to the classical masses of stable kinks arising in a massive non-linear -sigma model are computed. Ultraviolet divergences are controlled using…
Supersymmetry versus Integrability in two-dimensional Classical Mechanics
A. Alonso Izquierdo, M. A. González León, J. Mateos Guilarte +1
Supersymmetric extensions of Hamilton-Jacobi separable Liouville mechanical systems with two degrees of freedom are defined. It is shown that supersymmetry can be implemented in th…
Semi-classical mass of quantum k-component topological kinks
A. Alonso Izquierdo, W. Garcia Fuertes, M. A. Gonzalez Leon +1
We use the generalized zeta function regularization method to compute the one-loop quantum correction to the masses of the TK1 and TK2 kinks in a deformation of the O(N) linear sig…
Generalized Zeta Functions and One-loop Corrections to Quantum Kink Masses
A. Alonso Izquierdo, W. Garcia Fuertes, M. A. Gonzalez Leon +1
A method for describing the quantum kink states in the semi-classical limit of several (1+1)-dimensional field theoretical models is developed. We use the generalized zeta function…
Kinks from Dynamical Systems: Domain Walls in a Deformed O(N) Linear Sigma Model
A. Alonso Izquierdo, M. A. Gonzalez Leon, J. Mateos Guilarte
It is shown how a integrable mechanical system provides all the localized static solutions of a deformation of the linear O(N)-sigma model in two space-time dimensions. The proof i…
N=2 Supersymmetric Kinks and real algebraic curves
A. Alonso Izquierdo, M. A. Gonzalez Leon, J. Mateos Guilarte
The kinks of the (1+1)-dimensional Wess-Zumino model with polynomic superpotential are investigated and shown to be related to real algebraic curves.
