| Outline of Final Research Achievements |
We have investigated the thermal and quantum transport in superconductor/topological meterial hybrid systems theoretically and numerically. Due to the suppression of the Andreev reflection by the topological spin-momentum locking induced by the spin-orbit interaction, the cooling power of the system is found to be higher than that for conventional coolers. Therefore we can extract large amount of heat from normal metals. We also have investigated the electron transport in superconducting single-electron devices and found that the heating by thermal quasiparticles gives large influences on electron transport. In addition, we have theoretically investigated several properties of chiral topological superconductors, Josephson effect through anomalous hall insulator, and impurity effect in carrier doped topological insulators.
