Vortex ordering in fully-frustrated superconducting systems with dice lattice

By S. E. Korshunov

Abstract

The structure and the degeneracy of the ground state of a fully-frustrated XY-model are investigated for the case of a dice lattice geometry. The results are applicable for the description of Josephson junction arrays and thin superconducting wire networks in the external magnetic field providing halfinteger number of flux quanta per plaquette. The mechanisms of disordering of vortex pattern in such systems are briefly discussed
