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…
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 period…
Amplitude modulations and resonant decay of excited oscillons
F. Blaschke, T. Romańczukiewicz, K. Sławińska +1
We show that the decay of strongly excited oscillons in a single vacuum model reveals a chaotic, fractal-like pattern very much like one found in kink-antikink collision in the $ϕ^…
