摘要：
We consider the non-Abelian Hubbard chain in a magnetic field and chemical potential. We find that the set of different pseudoparticle types which generate the ground state from the suitable vacuum transform in the representation of the symmetry group U(1)circle times U(1), SU(2)circle times U(1), U(1)circle times SU(2), or SO(4) of the corresponding sector of parameter space.
