Unified theory of oscillons and modes
F. Blaschke, T. Romanczukiewicz, K. Slawinska +1
We show that an oscillon can be understood as a localized discrete resonant (non-normalizable) mode. Specifically, oscillon in the vacuum arises from the threshold mode, which beca…
Oscillons and bubbles in -ball dynamics
D. Canillas MartÃnez, P. Dorey, T. RomaÅczukiewicz +3
We show that, in the thin-wall regime, -ball--anti--ball collisions reveal chaotic behaviour. This is explained by the resonant energy transfer mechanism triggered by the int…
Excited oscillons and charge-swapping
A. Alonso-Izquierdo, D. Canillas MartÃnez, T. RomaÅczukiewicz +2
We show that the charge-swapping phenomenon can be understood as a real valued oscillon carrying an excitation in imaginary direction in the target space. Furthermore, we introduce…
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…
Oscillons from -balls through renormalization
F. Blaschke, T. RomaÅczukiewicz, K. SÅawiÅska +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…
Normal Modes of the Small-Amplitude Oscillon
Jarah Evslin, Tomasz Romanczukiewicz, Katarzyna Slawinska +1
Consider a classical (1+1)-dimensional oscillon of small amplitude . To all orders in , the oscillon solution is exactly periodic. We study small perturbations of such peri…
