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…

Large solitons flattened by small quantum corrections
Eduard Kim, Emin Nugaev, Yakov Shnir
We propose a general form of the UV-completed Friedberg-Lee-Sirlin (FLS) model. As can be seen from the mechanical interpretation, UV-completion allows thin-wall approximation for…

Nontopological Electromagnetic Hedgehogs
Yulia Galushkina, Emin Nugaev, Andrey Shkerin
We study classical localised configurations - solitons - in a theory of self-interacting complex Proca field with the global symmetry. We focus on spherically-symmetric soli…
