1306.3686 (Sho Nakosai et al.)

Two-dimensional p-wave superconducting states with magnetic moments on a
conventional s-wave superconductor

Sho Nakosai, Yukio Tanaka, Naoto Nagaosa
Unconventional superconductivity induced by the magnetic moments in a conventional spin-singlet s-wave superconductor is theoretically studied. By choosing the spin directions of these moments, one can design the spinless pairing states appearing within the s-wave energy gap. For example, with the non-collinear spin configurations, both $p_{x} + p_{y}$-wave and $p_{x} + i p_{y}$-wave like states can be realized. The nodes of the energy gap and the zero energy flat band of Majorana edge states exist in the former one, while it is found that chiral Majorana channel along the edge of the sample and the zero energy Majorana bound state at the core of the vortex appear in the latter case.
