Title: New models for asymmetric kinks and branes

Abstract

We investigate new models for scalar fields in flat and curved spacetime. We note that the global reflection symmetry of the potential that identify the scalar field model does not exclude the presence of internal asymmetries that give rise to asymmetric structures. Despite the asymmetry, the new structures are linearly stable and in the braneworld scenario with an extra dimension of infinite extend, they may generate new families of asymmetric thick branes that are robust against small fluctuations in the warped geometry. - Highlights: • Deformation method in defects models. • New Models for asymmetric kinks and branes are proposed. • Study of scalar fields in thick brane scenarios.
