Resumen
Topological solitons are relevant in several areas of physics. Recently, these configurations have been
investigated in contexts as diverse as hydrodynamics, Bose-Einstein condensates, ferromagnetism, knotted
light and non-Abelian gauge theories. In this paper we address the issue of wave propagation about a static
Hopf soliton in the context of the Nicole model. Working within the geometrical optics limit, we show that
several nontrivial lensing effects emerge due to nonlinear interactions as long as the theory remains
hyperbolic. We conclude that similar effects are very likely to occur in effective field theories characterized
by a topological invariant such as the Skyrme model of pions.
