We have numerically investigated the static properties of one-dimensional arrays of Josephson junctions connected in a square lattice containing a Josephson junction in each branch, accounting for self-field effects by means of self-inductances only. The static distribution of a single flux quantum and the critical current versus external magnetic field are calculated for different values of the SQUID parameter B-L = 2 pi L(C0)/Phi(0) of elementary cells. The presence of junctions in the horizontal branches significantly modifies the static properties, so that the behavior is characterized by a larger effective SQUID parameter

Abstract
We have numerically investigated the static properties of one-dimensional arrays of Josephson junctions connected in a square lattice containing a Josephson junction in each branch, accounting for self-field effects by means of self-inductances only. The static distribution of a single flux quantum and the critical current versus external magnetic field are calculated for different values of the SQUID parameter B-L = 2 pi L(C0)/Phi(0) of elementary cells. The presence of junctions in the horizontal branches significantly modifies the static properties, so that the behavior is characterized by a larger effective SQUID parameterFile in questo prodotto:
