Josephson current and Andreev states in superconductor–half metal–superconductor heterostructures
Josephson current and Andreev states in superconductor–half metal–superconductor heterostructures
We develop a detailed microscopic theory describing dc Josephson effect and Andreev bound states in superconducting junctions with a half metal. In such systems, the supercurrent is caused by triplet pairing states emerging due to spin-flip scattering at the interfaces between superconducting electrodes and the half metal. For sufficiently clean …
