Abstract
We compute the one-loop quantum corrections to the kink energies of the sinh-deformed 4 and 6 models in one space and one
time dimensions. These models are constructed from the well-known polynomial 4 and 6 models by a deformation procedure. We also
compute the vacuum polarization energy to the nonpolynomial function = 1 4 (1 − sinh2 .This potential approaches the model in
the limit of small values of the scalar function. These energies are extracted from scattering data for fluctuations about the kink solutions. We
show that for certain topological sectors with nonequivalent vacua the kink solutions of the sinh-deformed models are destabilized.
