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 …

A bstract We find supersymmetric extensions of the half-BPS soliton-impurity models in (1+
1) dimensions which preserve half of the\(\mathcal {N}\)= 1 supersymmetry. This is related to …

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 study the existence of Bogomol'nyi-Prasad-Sommerfield (BPS) configurations in a
restricted baby Skyrme-Maxwell enlarged via the inclusion of a nontrivial magnetic …

A bstract Bions are multiple fractional instanton configurations with zero instanton charge
playing important roles in quantum field theories on a compactified space with a twisted …

A bstract Construction of a supersymmetric extension of the Skyrme term was a long-
standing problem because of the auxiliary field problem; that is, the auxiliary field may …

We study the baby Skyrme model as a theory that interpolates between two distinct BPS
systems. For this, a near-BPS approximation can be used when there is a small deviation …

We investigate the existence and properties of kink-like solitons in a class of models with two
interacting scalar fields. In particular, we focus on models that display both double and …

A bstract We consider the Skyrme model in the near-BPS limit. The BPS part is made of the
sextic term plus a potential and the deformation is made of the standard massive Skyrme …

A bstract A supersymmetric extension of the Skyrme model was obtained recently, which
consists of only the Skyrme term in the Nambu-Goldstone (pion) sector complemented by …
