Quasiparticle cooling using a Topological insulator-Superconductor hybrid quantum wire junction

In this project we will investigate the thermoelectric properties of a hybrid junction realised in a topological insulator quantum wire hybridized with a conventional s-wave superconductor. We focus on the ballistic devices and study the quasiparticle flow, carrying both electric and thermal currents, adopting a scattering matrix approach based on conventional Blonder- Tinkham-Klapwijk formalism.
