So far we have used the picture of operators like H and p, acting on states like l rs) and Q/) in the Hilbert space Y. For developing perturbation theoretic expansions, however, it is useful to use the complementary concept of super-operators acting on Fock-space operators as defined in Sec. IIC. Using the super-operator H, the definition for the extended particle-hole Green s function of Eq. (23) can be written as... [Pg.83]
