Three-dimensional Josephson junction networks with coupling inhomogeneities in magnetic fields

The influence of coupling inhomogeneities on the static magnetic response of a three-dimensional 8 × 8 × 8 network of Josephson junctions is studied numerically. The inhomogeneities we consider are of two types. The first consists of an extended low-coupling-energy region in the network, the second...

Description
Summary:The influence of coupling inhomogeneities on the static magnetic response of a three-dimensional 8 × 8 × 8 network of Josephson junctions is studied numerically. The inhomogeneities we consider are of two types. The first consists of an extended low-coupling-energy region in the network, the second is realized by taking the in-plane superconducting coupling energy ten times higher that the coupling energy between planes. The present analysis is carried out for conventional 0-junctions.
