Topology-Induced Critical Current Enhancement in Josephson Networks
P. Silvestrini, R. Russo, V. Corato +7
We investigate the properties of Josephson junction networks with inhomogeneous architecture. The networks are shaped as "quare comb" planar lattices on which Josephson junctions l…

Evidence for a relativistic iron line in GRS 1915+105
A. Martocchia, G. Matt, V. Karas +2
We report on the discovery of a relativistic iron Kαfluorescent emission line in the BeppoSAX spectrum of the microquasar GRS 1915+105, taken on April 19, 1998, when the line was u…
