Vortices in Vacuumless Systems

الملخص EN

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.
