Abstract
We study the optimization of the superconducting properties of inhomogeneous nanowires.The main goal of this research is to find an optimized geometry that allows one tomaximize the desired property of superconductors, such as the maximum value of thelocal superconducting gap or total condensation energy. We consider the axiallysymmetric design of multilayered nanowires with the possibility of adjusting andchanging the layer thickness. We use numerical solution of the Bogoliubov–de Gennesequations to obtain the local superconducting gap for different arrangements ofinhomogeneous structures. The values of the optimized properties can be up to300% greater than for a non-optimized geometry. The optimized configuration of multilayersstrongly depends on the desired property one wants to optimize and on the number oflayers in the nanowire.
