Query: Generalized slave-particle method for extended Hubbard models   We introduce a set of generalized slave-particle models for extended Hubbard
models that treat localized electronic correlations using slave-boson
decompositions. Our models automatically include two slave-particle methods of
recent interest, the slave-rotor and slave-spin methods, as well as a ladder of
new intermediate models where one can choose which of the electronic degrees of
freedom (e.g., spin or orbital labels) are treated as correlated degrees of
freedom by the slave bosons. In addition, our method removes the aberrant
behavior of the slave-rotor model at weak correlation strength by removing the
contribution of unphysical states from the bosonic Hilbert space. The
flexibility of our formalism permits one to separate and isolate the effect of
correlations on the key degrees of freedom.
