Geometric Construction of non-linear Sigma models with Q-ball/Q-kink solutions
A. Alonso-Izquierdo, D. Canillas Martinez, C. Garzon Sanchez +1
Non-linear Sigma models involving U(1) symmetry group are studied using a geometrical formalism. In this type of models, Q-balls and Q-Kinks solutions are found. The geometrical fr…
Wobbling kinks and shape mode interactions in a coupled two-component theory
A. Alonso-Izquierdo, D. Miguélez-Caballero, L. M. Nieto
The dynamics of a wobbling kink in a two-component coupled scalar field theory (with an excited orthogonal shape mode) is addressed. For this purpose, the vibration spectrum…
Topological and non-topological kink families in non-linear -Sigma models
A. Alonso-Izquierdo, A. J. Balseyro Sebastian, M. A. Gonzalez Leon
In this paper we construct a family of Hamilton-Jacobi separable non-linear Sigma models for which the kink variety can be analytically identified…
Defects composed of kinks and Q-balls: analytical solutions and stability
A. Alonso-Izquierdo, C. Garzon Sanchez
In this paper all the defect-type solutions in a family of scalar field theories with a real and a complex field in (1+1) dimensional Minkowski spacetime have been analytically ide…
Non-topological fractional fermion number in the Jackiw-Rossi model
Caio Almeida, Alberto Alonso-Izquierdo, Rodrigo Fresneda +2
We compute the vacuum fermion current in dimensional Jackiw-Rossi model by using the expansion. The current is expressed through a weighted -function with a matrix…
Two species of semi-local cosmic strings in Abelian gauged -sigma models coupled to gravity
A. Alonso-Izquierdo, W. García Fuertes, J. Mateos Guilarte
We study a semi-local Abelian Higgs sigma model with -valued scalar fields coupled to gravity. We establish the conditions needed for self-duality in this system and…
