Spin rotation invariant spin triplet superconducting liquids

Zhou, Fei

Original · EN

Spin ordering and its effect on the low energy quasiparticles in a p-wave superconducting fluid are investigated. We study the properties of a new 2D quantum spin triplet superconducting liquid where the ground state is spin rotation invariant. In quantum spin disordered cases, zero energy skyrmions are topologically stable because of a fermionic zero mode in space-time monopoles which serve as a quantum protectorate.The low energy quasiparticles are bound states of the bare Bogolubov- De Gennes (BdeG)quasiparticles and skyrmions, which are charge neutral bosons at the zero energy limit. Further more, the spin collective excitations are fractionalized ones carrying a half spin and obeying fermionic statistics. In thermally spin disordered superconducting states, a bare BdeG has an infinity energy and each two BdeG quasiparticles form spin zero or one bound states.
