21 Apr 2012 | | Abstract: | We clarify the interplay of a Zeeman magnetic field and dipole interaction on
surface helical Majorana fermions of superfluid 3He-B. We first reveal that the
B-phase under a magnetic field in a particular direction stays topological due
to a discrete symmetry, that is, in a symmetry protected topological phase. It
is shown that the Ising spin character of the helical Majorana fermion is a
direct consequence of the symmetry protected topological phase. Based on the
quasiclassical theory, we demonstrate that the competition between the dipole
interaction and the magnetic field involves the topological phase transition
and simultaneously the spontaneous symmetry breaking of the discrete symmetry,
which is accompanied by novel behaviors of spin susceptibilities on the
surface. | | Source: | arXiv, 1204.4780 | | Services: | Forum | Review | PDF | Favorites | |
