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…
Gauged compact -balls and -shells in a multi-component model
P. Klimas, L. C. Kubaski, N. Sawado +1
We study a multicomponent model's scalar electrodynamics. The model contains -balls and -shells, which are nontopological compact solitons with time dependency $e^{iωt…
Nodal compact -ball/-shell in the nonlinear sigma model
P. Klimas, N. Sawado, S. Yanai
Nodal, excited compactons in the models with V-shaped potentials are analyzed. It is shown that the solutions exist as compact -balls and -shells. The solutio…
Compact Q-balls and Q-shells in a multi-component model
P. Klimas, L. C. Kubaski, N. Sawado +1
Coupled multi-component models with V-shaped potentials are analyzed. It is shown that the model has solutions being combinations of compact Q-balls and Q-shells. T…
Phase analyses for compact, charged boson stars and shells harboring black holes in the nonlinear sigma model
Nobuyuki Sawado, Shota Yanai
Phase diagrams of the boson stars and shells of the gauged nonlinear sigma model are studied. The solutions of the model exhibit both the ball- and the shell…
Compact, charged boson-stars, -shells in the gravitating nonlinear sigma model
Nobuyuki Sawado, Shota Yanai
We study gauged gravitating compact -ball, -shell solutions in a nonlinear sigma model with the target space . The models with odd integer and a spe…
Gravitating compact -ball and -shell solutions in the nonlinear sigma model
Pawel Klimas, Nobuyuki Sawado, Shota Yanai
We study compact gravitating -ball, -shell solutions in a sigma model with the target space . Models with odd integer and suitable potential can be paramet…
