"Out-of-equilibrium conductance of metal-superconductor junctions : Application to Au-Ba(Fe,Ni)2As2 point contacts"

Abstract

Point contact spectroscopy is an electrical measurement technique that is frequently applied to the study of superconductors. It is based on the electrical characterization of nanocontacts between a known material, such as a metal, and the sample under study. However, such highly localized electrical current injection may also locally perturbate the sample, leading to the emergence of complex out-of-equilibrium physics. In my defense, I will describe the theoretical and experimental study of this phenomenology which I have carried out during my PhD, along with possible implications for the study of iron pnictide superconductors.
