The Universal Floquet Modes of (Quasi)-Breathers and Oscillons
Jarah Evslin, Tomasz Romańczukiewicz, Katarzyna Slawińska +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. Romańczukiewicz, K. Sławińska +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…

Kink Moduli Spaces -- Collective Coordinates Reconsidered
N. S. Manton, K. Oleś, T. Romańczukiewicz +1
Moduli spaces - finite-dimensional, collective coordinate manifolds - for kinks and antikinks in theory and sine-Gordon theory are reconsidered. The field theory Lagrangian r…
