Description

One of the most fundamental questions in physics is how the macroscopic properties of matter emerge from microscopic constituents. In this talk, I will discuss a “bottom-up” approach to studying collective effects in materials via arrays of coupled superconducting islands. We fabricate large arrays of superconducting islands patterned on normal metal films; by changing configuration of the islands, we can tune parameters relevant to 2D superconductivity, such as disorder, dissipation, and phase separation. I will discuss electrical transport measurements of these systems, including evidence of an unusual metallic ground state, as well as the unexpected suppression of superconductivity in large granular islands.
