Quantum Oscillons are Long-Lived
Jarah Evslin, Katarzyna SlawiÅska, Tomasz RomaÅczukiewicz +1
As the longest lived transient, oscillons play a critical role in classical field theory simulations of many phenomena. However, beyond the classical approximation, it is well-know…
Linearized Q-Ball Perturbations
Jarah Evslin, Hui Liu, Tomasz RomaÅczukiewicz +3
Linearized deformations of the thick-walled (low-amplitude) (1+1)-dimensional Q-ball may be decomposed into relativistic modes, which are roughly plane waves, and also long-wavelen…
The Universal Floquet Modes of (Quasi)-Breathers and Oscillons
Jarah Evslin, Tomasz RomaÅczukiewicz, Katarzyna SlawiÅska +1
Just as linearized perturbations of time-independent configurations can be decomposed into normal modes, those of periodic systems can be decomposed into Floquet modes, which each…
Oscillons from -balls
F. Blaschke, T. RomaÅczukiewicz, K. SÅawiÅska +1
Using Renormalization Group Theory we show that oscillons in (1+1)-dimensions can be obtained, at the leading nonlinear order, from -balls of universal complex field theories. F…
