Comment on “Z2-slave-spin theory for strongly correlated fermions”
The authors of Ref. 1 introduced a new slave-spin (SS) mean-field (MF) approach to the Hubbard model of strongly correlated electrons in terms of Ising spins and standard fermion operators by constructing an enlarged Hilbert space with both physical and unphysical states. The purpose of this co...
