Vortex ordering in fully frustrated superconducting systems with a dice lattice
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 half-integer number of flux quanta per plaquette. The mechanisms of disordering of vortex pattern in such systems are briefly discussed.
