An SO(5) model of p-wave superconductivity and ferromagnetism
arXiv:cond-mat/9811001 · doi:10.1103/PhysRevLett.82.2939
Abstract
We study an SO(5) model unifying p-wave superconductivity and ferromagnetism. If only a single p-wave pairing wavefunction is involved, the p-wave superconducting (pSC) and ferromagnetic (F) states can be unified to form 10-dimensional multiplet of SO(5). The collective modes in pSC and F states are studied from this viewpoint in terms of a non-linear sigma model.
