Localized Electromagnetic Perturbations on Vector Solitons
Yulia Galushkina, Eduard Kim, Emin Nugaev +1
Using effective field theory approach one can describe localization of electromagnetic field on a non-topological soliton. Pursuing this aim we consider the U(1) gauge theory with…

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…
