Optimization of the design of superconducting inhomogeneous nanowires

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 to maximize the desired property of superconductors, such as the maximum value of the local superconducting gap or total condensation energy. We consider the axially symmetric design of multilayered nanowires with the possibility of adjusting and changing the layer thickness. We use numerical solution of the Bogoliubov-de Gennes equations to obtain the local superconducting gap for different arrangements of inhomogeneous structures. The values of the optimized properties can be up to 300% greater than for a non-optimized geometry. The optimized configuration of multilayers strongly depends on the desired property one wants to optimize and on the number of layers in the nanowire.
