Scattering of metastable lumps in a model with a false vacuum
Fred C. Lima, Fabiano C. Simas, K. Z. Nobrega +1
In this work we consider the scalar field model with a false vacuum proposed by A. T. Avelar, D. Bazeia, L. Losano and R. Menezes, Eur. Phys. J. C 55, 133-143 (2008). The model dep…
Solitary oscillations and multiple antikink-kink pairs in the double sine-Gordon model
Fabiano C. Simas, Fred C. Lima, K. Z. Nobrega +1
We study kink-antikink collisions in a particular case of the double sine-Gordon model depending on only one parameter . The scattering process of large kink-antikink shows the…
Oscillons in hyperbolic models
D. Bazeia, Adalto R. Gomes, K. Z. Nobrega +1
In this work we examine kink-antikink collisions in two distinct hyperbolic models. The models depend on a deformation parameter, which controls two main characteristics of the pot…
Kink scattering in hyperbolic models
D. Bazeia, Adalto R. Gomes, K. Z. Nobrega +1
In this work we study kink-antikink and antikink-kink collisions in hyperbolic models of fourth and sixth order. We compared the patterns of scattering with known results from poly…
Boundary scattering in the model
Fred C. Lima, Fabiano C. Simas, K. Z. Nobrega +1
We study the non-integrable model on the half-line. The model has two topological sectors. We chose solutions from just one topological sector to fix the initial conditions…
False vacuum decay in kink scattering
Adalto R. Gomes, F. C. Simas, K. Z. Nobrega +1
In this work we consider kink-antikink and antikink-kink collisions in a modified model with a false vacuum characterized by a dimensionless parameter . The usual mo…
