Josephson junctions are the result of separating two superconductors with a non-superconducting material. Josephson junction arrays are an extension of this idea where we use hundreds of superconducting ‘islands’, placed in a grid, to form a large number of Josephson junctions. There has been renewed interest in such arrays lately for a few reasons. One is the potential application to qubits. Another reason is that these arrays work as testbeds in which we can model different physical systems. In this talk, I will introduce the Josephson junction arrays and their primary characteristics. Then, I will discuss the work our group has done to use these arrays to look at the physics of vortex motion in superconductors.
