Query: Fermionic bound states in distinct kinklike backgrounds   This work deals with fermions in the background of distinct localized
structures in the two-dimensional spacetime. Although the structures have
similar topological character, which is responsible for the appearance of
fractionally charged excitations, we want to investigate how the geometric
deformations that appear in the localized structures contribute to the change
in the physical properties of the fermionic bound states. We investigate the
two-kink and compact kinklike backgrounds, and consider two distinct
boson-fermion interactions, one motivated by supersymmetry and the other
described by the standard Yukawa coupling.
