Oscillons and bubbles in -ball dynamics
D. Canillas Martínez, P. Dorey, T. Romańczukiewicz +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…

Perturbations of Q-balls: from spectral structure to radiation pressure
Dominik Ciurla, Patrick Dorey, Tomasz Romańczukiewicz +1
We investigate Q-balls in a 1+1 dimensional complex scalar field theory. We find that the relaxation of a squashed Q-ball is dominated by the decay of a normal mode through nonline…

Oscillons in gapless theories
P. Dorey, T. Romanczukiewicz, Y. Shnir +1
We show that large scale oscillons, i.e., quasi-periodic, long living particle like solutions, may exist in massless theories, too. Their existence is explained using an effective…
