| dc.description | The electronic structure of domain walls in superconductors is computed as a function of temperature within Bogoliubov-de Gennes theory. We find a spontaneous interface transition at an ultralow temperature T<sub>*</sub> 10<sup>-2</sup> T <sub>c</sub> , in which the self-consistent pair potential transforms from a smooth Ginzburg-Landau form into one showing oscillatory Friedel-like behaviour. The transition is associated with a lifting of the energy of midgap excitations and the formation of an energy minigap. Like the bulk superconducting phase transition at T <sub>c</sub> , this midgap transition is manifested as a pronounced peak in the specific heat of the domain-wall matter. The transition is also predicted to occur in thin SNS (superconducting-normal-superconducting) Josephson -junctions. |
