Dyson equation for spin Green's functions

V. G. Bar'yakhtar, V. N. Krivoruchko, D. A. Yablonskii


Abstract: It is shown that Dyson's method for separating irreducible diagrams can be used in the diagram technique for spin operators. This method is used to obtain an equation for the transverse spin Green's function of a Heisenberg ferromagnet.
