| Research Abstract |
It was revealed that the Andreev bound states formed at the surfaces of superfluid 3He show strongly anisotropic response to magnetic field. Moreover, we pointed out that the odd-frequency Cooper pair is closely related to the zero mode of the Andreev bound states. From this viewpoint, we reexamined previous experiments on the Andreev bound states in superfluid 3He and revealed that there in fact exist the odd-frequency Cooper pairs near the surfaces of superfluid 3He.
