Abstract

We study the nucleation of single vortices in a 2D channel in a superconducting/superfluid state which connects two bulk samples. Using real space renormalization group techniques, we show that boundary effects associated with the nucleation of single vortices drives the system to a phase transition at a temperature lower than the Berezinskǐ-Kosterlitz-Thouless temperature.
