Solitons emerge in various non-linear systems as stable localized configurations, behaving
in many ways like particles, from non-linear optics and condensed matter to nuclear physics …

The Skyrme model is a low-energy effective field theory for QCD, where the baryons emerge
as soliton solutions. It is, however, not so easy within the standard Skyrme model to …

Within the class of field theories with the field content of the Skyrme model, one submodel
can be found which consists of the square of the baryon current and a potential term only …

The magnetic skyrmion is described by one control parameter and one length scale. We
study the two extreme limits of the control parameter, infinitely large and vanishing, and find …

A restriction of the baby Skyrme model consisting of the quartic and potential terms only is
investigated in detail for a wide range of potentials. Further, its properties are compared with …

We investigate the existence of self-dual configurations in the restricted gauged baby
Skyrme model enlarged with a Z 2–symmetry, which introduces a real scalar field. For such …

We study the higher derivative chiral models with four supercharges and Bogomol'nyi–
Prasad–Sommerfield (BPS) states in these models. The off-shell Lagrangian generically …

We investigate two types of excited oscillons. We first focus on spherical symmetry and find
that there are a tower of spherical oscillons with higher energies. Despite having multiple …

The static baby Skyrme model is investigated in the extreme limit where the energy
functional contains only the potential and Skyrme terms, but not the Dirichlet energy term. It …
