    • note
    • iσ can be thought as electron-creation operators with spin -σ acting on a vacuum with a Zhang-Rice singlet at every site. If the Zhang-Rice singlets were represented by doubly occupied sites as in Ref. [11], all t's would change sign. In Ref. [18], a minus sign precedes the hopping terms in the hamiltonian.
