Generalized Models for Spinning Field Lumps on Plane
Yulia Galushkina, Eduard Kim, Emin Nugaev +1
We study planar non-topological solitons in models with nonlinear potentials that are bounded from below. These models provide consistent completion for the classical consideration…
CFT-approach to Rotating Field Lumps in Attractive Potential
Yulia Galushkina, Eduard Kim, Emin Nugaev +1
We demonstrate the importance of relativistic corrections for the study of the stability of -dimensional non-topological solitons with quartic self-interaction in the low-en…
Properties of Non-topological Solitons in Two-dimensional Model With Resurrected Conformal Symmetry
Yulia Galushkina, Eduard Kim, Emin Nugaev +1
We study properties of non-topological solitons in two-dimensional conformal field theory. The spectrum of linear perturbations on these solutions is found to be trivial, containin…
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…
