  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.
