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.…

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…

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…
