Query: Vortices in vacuumless systems   We investigate the presence of vortex solutions in potentials without vacuum
state. The study is conducted considering Maxwell and Chern-Simons dynamics.
Also, we use a first order formalism that helps us to find the solutions and
their respective electromagnetic fields and energy densities. As a bonus, we
get to calculate the energy without knowing the explicit solutions. Even though
the solutions present a large "tail" which goes far away from the origin, the
magnetic flux remains a well defined topological invariant.
