Point contact spectroscopy is an electrical measurement technique that is frequently applied to the study o f 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.
