| Research Abstract |
We have experimentally verified that a quantum point contact with a spin-orbit interaction works as a perfect spin polarizer. In the Andreev bound states, which appear in a normal conductor bounded by two superconductors, we have found that the spin Hall effect induced by a transverse current greatly reduces the anomalous conductance due to the Andreev reflection.
