Research Abstract |
In the experimental study of anisotropic superfluid 3He, we observed a new vortex in a narrow tube, a new superfluid phase, a new phase transition and a new energy dissipation mechanism in impurities by controlling the order parameters of spin triplet p-wave superfluid 3He with using a confined space as the external circumstance and impurities as the internal circumstance. In the theoretical study, we established a quasi-classical Green's function method and pointed out that the surface bound state in superfluid 3He causes many interesting phenomena. And we also expected the possibility of the existence of odd frequency pair in inpurities as a proximity effect.
