Resumen:
We have investigated the sizedependence of the ground state energy as a function of the magnetic field inJosephson junction arrays with open boundaries. We present a simple rings modelthat reproduces with great confidence the size and field dependence of theenergy of the system obtained by numerical simulation of the Hamiltonian. Fromthese results we obtained the size dependence of the first penetration field,where the one-vortex state becomes favorable compared to the zero-vortex state.
