Scalar fields, impurities and supersymmetry
D. Bazeia, A. C. Lehum, G. S. Santiago
We develop a rigid superspace formulation for multifield scalar models coupled to localized impurities through spurion superfields in two-dimensional spacetime.…
Geometrically constrained multi-kink configurations in generalized impurity-doped field theories
D. Bazeia, M. A. Liao, M. A. Marques
This short communication investigates impurity coupling in generalized field theories where scalar coupling is introduced directly at the level of the kinetic and gradient contribu…
Half-BPS Impurity Backgrounds and Supersymmetry
D. Bazeia, A. C. Lehum
We develop a rigid superspace framework for spatially inhomogeneous impurity deformations in dimensions by embedding the impurity profile into a real b…
Localized structures in two-field systems: exact solutions in the presence of Lorentz symmetry breaking and explicit connection with geometric constraints
G. H. Bandeira, D. Bazeia, G. S. Santiago +1
We investigate a class of models described by two real scalar fields in two-dimensional spacetime. The study focuses mainly on the presence of exact static solutions which satisfy…
Nonlinear Dynamics of Kink Configurations: From Small to Large Kink Collisions
Aliakbar Moradi Marjaneh, Dionisio Bazeia
This study explores the scattering dynamics of kinks within a nonlinear system governed by a parameterized potential , examining the distinct behaviors of small and large…
Exact solutions for a complex scalar field under discrete symmetry
D. Bazeia, R. Menezes, G. S. Santiago
We report on the presence of families of exact solutions for a complex scalar field that behaves according to the rules of discrete symmetry. Since the family of models is ex…
