Mode engineering with a one-dimensional superconducting metamaterial
Mode engineering with a one-dimensional superconducting metamaterial
We propose a way to control the Josephson energy of a single Josephson junction embedded in a one-dimensional superconducting metamaterial: an inhomogeneous superconducting loop, made out of a superconducting nanowire or a chain of Josephson junctions. The Josephson energy is renormalized by the electromagnetic modes propagating along the loop. We …
