• Abstract: Superconducting interfaces have recently been demonstrated to contain a rich variety of effects that give rise to sizable thermoelectric responses and unexpected thermal properties, despite traditionally being considered poor thermoelectrics due to their intrinsic electron-hole symmetry. We review different mechanisms driving this response in hybrid normal-superconducting junctions, depending on the dimensionality of the mesoscopic interface. In addition to discussing heat to power conversion, cooling and heat transport, special emphasis is put on physical properties of hybrid devices that can be revealed by the thermoelectric effect.

• Extrinsic thermoelectric response of coherent conductors [0.0]
  Coupling to the probe has the dual effect of allowing for the controlled local injection of heat currents into the system. Considering a simple model for noninteracting electrons, we find a nonlocal thermoelectric response which is modulated by the position of the hot probe tip. A separate investigation of the effects of dephasing and of quasielastic scattering gives further insights into the different mechanisms involved.
