    • Using the constraint condition, we replace Siz=fifidag(bi uarrow bi uarrow dag -bi darrow bi darrow dag ) by Siz=fifidag(2S-2bi darrow bi darrow dag -fidagfi) = fifidag(2S-bi darrow bi darrow dag ).

    • Neglected terms in Eq. (2.7) are -(N/2) JS2z + JSz tsumk vec ( curlepk vec -1) +(JS2z-JSz curlepav) tsumk vec (fk vec a dag fk vec a + fk vec b dag fk vec b), with curlepav=(2/N) tsump vec ( curlepp vec -1). These terms give rise to only a constant shift to the excitation energy of hole.

    • There appears a strongly hybridized mode which is characterized for the spiral phase, as discussed in Ref. 27.
