Book excerpt: "The phase sensitivity of the Josephson effect makes it a powerful tool to probe superconductors with unusual properties. In this thesis, we study three different setups that highlight the usefulness of the Josephson effect to find experimental signatures of unconventional and topological superconductivity. The first studied setup consist of a tunnel junction between an s-wave and an unconventional s± superconductor. The second studied setup is a topological version of a Josephson junction ring coupled to a quantum dot. The third and final setup is a topological Josephson junction in the presenceof phase fluctuations caused by charging effects. While this thesis comprises of studies of different materials, the results from the three projects presented here exhibit: a) how the Josephson tunneling can be used to probe superconductors with unusual properties and b) the need for theoretical models of Josephson tunneling that account for variationsand fluctuations of the superconducting order parameter." --
