Cluster-based superconducting tunneling networks

A two-dimensional tunneling network consisting of nanoclusters placed on a surface is studied. It is shown that such a network is capable of transferring a large supercurrent at high temperatures. For a realistic set of parameters the damping is quite small, and the smallness is due to strong renorm...

Zusammenfassung:A two-dimensional tunneling network consisting of nanoclusters placed on a surface is studied. It is shown that such a network is capable of transferring a large supercurrent at high temperatures. For a realistic set of parameters the damping is quite small, and the smallness is due to strong renormalization of the capacitance of a cluster. The critical field also turns out to be large.
