Q-ball polarization -- a smooth path to oscillons
F. Blaschke, T. Romanczukiewicz, K. Slawinska +1
We show that in the complex theory the oscillon, together with its spectral structure and the amplitude modulation, arises from the exited Q-ball carrying the bound and the q…
Spinning boson stars in nonlinear sigma models and Universal Relations
Christoph Adam, Jorge Castelo Mourelle, Alberto García Martín-Caro +1
Boson stars are hypothetical compact objects derived from solutions of a self-gravitating complex scalar field. In this study, we extend the traditional models by generalizing the…
Instanton Corrections to the MSTB Kink Mass
Jarah Evslin, Alberto García Martín-Caro, Andrzej Wereszczyński
The Montonen-Sarker-Trullinger-Bishop (MSTB) model enjoys two classically degenerate kink solutions in the same topological sector. We construct the instanton that interpolates bet…
Feshbach resonances and dynamics of BPS solitons
Alberto García Martín-Caro, Jose Queiruga, Andrzej Wereszczynski
We demonstrate that the geodesic dynamics of BPS solitons can be modified by the excitation of Feshbach resonances, or quasi-bound modes, in a toy model of two scalar fields. A mod…
Oscillons from -balls through renormalization
F. Blaschke, T. Romańczukiewicz, K. Sławińska +1
Using a renormalization-inspired perturbation expansion we show that oscillons in a generic field theory in (1+1) dimensions arise as dressed -balls of a universal (up to the le…
Universal Relations for Rotating Scalar and Vector Boson Stars
Christoph Adam, Jorge Castelo Mourelle, Etevaldo dos Santos Costa Filho +2
Bosonic stars represent a hypothetical exotic type of compact stellar objects that could be observed from the gravitational signal of coalescing binaries in current and future grav…
