Abstract

In this work we investigate lump-like solutions in models described by a single real scalar field. We start considering non-topological solutions with the usual lump-like form, and then we study other models, where the bell-shape profile may have a varying amplitude and width or develop a flat plateau at its top or even induce a lump on top of another lump. We suggest possible applications in which these exotic solutions might be used in several distinct branches of physics.
