| Popis: | A superconducting heterojunction made of a p-wave superconductor and a normal s-wave superconductor is investigated. The Bogoliubov transformation for the p-wave superconductor was obtained by diagonalizing the superconducting Hamiltonian. The value of the Josephson current that flows in the heterojunctions of p-wave/s-wave superconductors was calculated with this Bogoliubov transformation and was shown to be zero in the first-order perturbation at 0 K and at finite temperature. The ground state of the Balian-Werthamer-state superconductor at 0 K was obtained in the second-quantization formalism. |
