Fourier analysis of compact oscillons
Pawel Klimas, Leandro Roza Livramento, João Saldanha Streibel
We present a new derivation of the exact compact oscillon in the signum-Gordon model using Fourier methods. This approach decomposes the oscillon into an infinite, uniformly conver…
Compact Q-balls and Q-shells within a Skyrme-Faddeev type model
E. L. Colaço, P. Klimas, L. R. Livramento +2
While models with analytic potentials are known to support finite-energy compact Q-ball and Q-shell solutions, their behavior in more complex Lagrangian frameworks remains a…
Self-duality and the Holomorphic Ansatz in Generalized BPS Skyrme Model
L. A. Ferreira, L. R. Livramento
We propose a generalization of the BPS Skyrme model for simple compact Lie groups that leads to Hermitian symmetric spaces. In such a theory, the Skyrme field takes its values…
Harmonic, Holomorphic and Rational Maps from Self-Duality
L. A. Ferreira, L. R. Livramento
We propose a generalization of the so-called rational map ansatz on the Euclidean space , for any compact simple Lie group such that …
Solitons in the Gauged Skyrme-Maxwell Model
Leandro Roza Livramento, Eugen Radu, Yakov Shnir
We consider soliton solutions of the U(1) gauged Skyrme model with the pion mass term. The domain of existence of gauged Skyrmions is restricted from above by the value of the pion…
A Quasi Self-Dual Skyrme Model
L. A. Ferreira, L. R. Livramento
It has been recently proposed a modification of the Skyrme model which admits an exact self-dual sector by the introduction of six scalar fields assembled in a symmetric, positive…
False vacuum Skyrmions revisited
L. R. Livramento, Ya. Shnir
We consider the classical static soliton solutions of the Skyrme model with false vacuum potential. We make use of fully three-dimensional relaxation calculations to construct glob…
Self-Duality in the Context of the Skyrme Model
L. A. Ferreira, L. R. Livramento
We study a recently proposed modification of the Skyrme model that possesses an exact self-dual sector leading to an infinity of exact Skyrmion solutions with arbitrary topological…
Compact Q-balls and Q-shells in the CPN type models
P. Klimas, L. R. Livramento
We show that the CPN model with odd number of scalar fields and V-shaped potential possesses finite energy compact solutions in the form of Q-balls and Q-shells. The solutions were…
