Abstract

Spin ordering and its effect on low-energy quasiparticles in a p-wave superconducting liquid are investigated. We study the properties of a two-dimensional (2D) p-wave superconducting liquid where the ground state is spin rotation invariant. In quantum spin disordered liquids, the low-energy quasiparticles are bound states of the bare Bogolubov–De Gennes (BdeG) quasiparticles and zero energy skyrmions, which are charge neutral bosons at the low-energy limit. Further more, spin collective excitations are fractionalized ones carrying a half-spin and obeying fermionic statistics. In thermally spin disordered limits, the quasiparticles are bound states of bare BdeG quasiparticles. The latter situation can be realized in some layered p-wave superconductors where the spin-orbit coupling is weak.
