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…

Resonant kink-antikink scattering through quasinormal modes
Patrick Dorey, Tomasz Romańczukiewicz
We investigate the role that quasinormal modes can play in kink-antikink collisions, via an example based on a perturbation of the model. We find that narrow quasinormal mode…

Could the primordial radiation be responsible for vanishing of topological defects?
Tomasz Romańczukiewicz
We study the motion of topological defects in 1+1 and 2+1 d relativistic model with three equal vacua in the presence of radiation. We show that even small fluctuations can t…
